REVENUE

6 Months Ended

Jun. 30, 2024

Revenue from Contract with Customer [Abstract]

REVENUE

Sun Country is a certificated air carrier generating Operating Revenues from Scheduled Service, Charter, Ancillary, Cargo and Other revenue. Scheduled Service revenue mainly consists of base fares. Charter revenue is primarily generated through service provided to the U.S. Department of Defense ("DoD"), collegiate and professional sports teams, and casinos. Ancillary revenues consist of revenue earned from air travel-related services, such as: baggage fees, seat selection fees, other fees and on-board sales. Cargo consists of revenue earned from flying cargo aircraft for Amazon.com Services, Inc. (together with its affiliates, “Amazon”) under the Amended and Restated Air Transportation Services Agreement (the “A&R ATSA”). Other revenue consists primarily of revenue from services in connection with Sun Country Vacations products and rental revenue related to certain transactions where the Company serves as a lessor. The Company recognized rental revenue of $9,873 and $5,871, during the three months ended June 30, 2024 and 2023, respectively; and $19,148 and $5,949 during the six months ended June 30, 2024 and 2023, respectively.

During the three months ended June 30, 2024, the Company entered into the A&R ATSA with Amazon that will increase the number of 737-800 cargo aircraft that Sun Country operates on behalf of Amazon from 12 to 20. The A&R ATSA includes revised economics to reflect the higher-cost environment that has ensued since the original Air Transportation Services Agreement ("ATSA") was signed in December 2019. The performance obligations under the A&R ATSA are unchanged from the original ATSA. The first additional

aircraft are expected to begin service in the first quarter of 2025. All eight aircraft are expected to be operational by the end of the third quarter of 2025. The A&R ATSA includes an initial six-year term, which runs until October 2030. The agreement includes two additional, two-year renewal terms exercisable at Amazon's option, and a subsequent three-year renewal term subject to mutual written agreement, which, if not agreed to, will trigger a final two-year wind-down term. Amazon did not make any incremental payments for start-up costs in connection with the signing of the A&R ATSA. The warrant agreement was not amended, and Amazon did not receive any additional warrants.

The significant categories comprising Operating Revenues are as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Scheduled Service	$	88,078	$	111,467	$	229,272	$	264,124
Charter	51,009		49,626		98,321		95,813
Ancillary	77,308		66,773		163,466		135,198
Passenger	216,395		227,866		491,059		495,135
Cargo	25,447		25,017		49,395		48,378
Other	12,539		8,203		25,410		11,688
Total Operating Revenues	$	254,381	$	261,086	$	565,864	$	555,201

The Company attributes and measures its Operating Revenues by geographic region as defined by the United States Department of Transportation ("DOT") for airline reporting based upon the origin of each passenger and cargo flight segment.

The Company’s operations are highly concentrated in the U.S., but include service to many international locations, primarily based on scheduled service to Latin America during the winter season and on military charter services.

Total Operating Revenues by geographic region are as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Domestic	$	247,898	$	251,582	$	538,112	$	526,071
Latin America	6,483		9,451		27,752		28,555
Other	—		53		—		575
Total Operating Revenues	$	254,381	$	261,086	$	565,864	$	555,201

Contract Balances

The Company’s contract assets primarily relate to costs incurred to get Amazon cargo aircraft ready for service under the original ATSA. The balances are included in Other Current Assets and Other Assets on the Condensed Consolidated Balance Sheets.

The Company’s contract liabilities are comprised of: 1) ticket sales for transportation that have not yet been provided (reported as Air Traffic Liabilities on the Condensed Consolidated Balance Sheets), 2) outstanding loyalty points that may be redeemed for future travel and other non-air travel awards (reported as Loyalty Program Liabilities on the Condensed Consolidated Balance Sheets) and, 3) the Amazon Deferred Up-front

Payment received (reported within Other Current Liabilities and Other Long-term Liabilities on the Condensed Consolidated Balance Sheets).

Contract Assets and Liabilities are as follows:


	June 30, 2024		December 31, 2023
Contract Assets
Amazon Contract	$	1,099	$	1,493
Total Contract Assets	$	1,099	$	1,493

Contract Liabilities
Air Traffic Liabilities	$	116,877	$	157,996
Loyalty Program Liabilities	13,272		13,737
Amazon Contract	1,811		2,225
Total Contract Liabilities	$	131,960	$	173,958

The balance in the Air Traffic Liabilities fluctuates with seasonal travel patterns. Most tickets can be purchased no more than twelve months in advance, therefore any revenue associated with tickets sold for future travel will be recognized within that timeframe. For the six months ended June 30, 2024, $147,256 of revenue was recognized in Passenger revenue that was included in the Air Traffic Liabilities as of December 31, 2023.

Loyalty Program

The Sun Country Rewards program provides loyalty awards to program members based on accumulated loyalty points. The Company records a liability for loyalty points earned by passengers under the Sun Country Rewards program using two methods: 1) a liability for points that are earned by passengers on purchases of the Company’s services is established by deferring revenue based on the redemption value, net of estimated loyalty points that will expire unused, or breakage; and 2) a liability for points attributed to loyalty points issued to the Company’s Visa card holders is established by deferring a portion of payments received from the Company’s co-branded agreement. The balance of the Loyalty Program Liabilities fluctuates based on seasonal patterns, which impacts the volume of loyalty points awarded through travel or issued to co-branded credit card and other partners (deferral of revenue) and loyalty points redeemed (recognition of revenue). Due to these reasons, the timing of loyalty point redemptions can vary significantly.

Changes in the Loyalty Program Liabilities are as follows:


	2024		2023
Balance – January 1	$	13,737	$	15,437
Loyalty Points Earned	4,519		4,262
Loyalty Points Redeemed (1)	(4,984)		(6,043)
Balance – June 30	$	13,272	$	13,656

______________________


(1)			Loyalty points are combined in one homogenous pool, which includes both air and non-air travel awards, and are not separately identifiable. As such, the revenue recognized is comprised of points that were part of the Loyalty Program Liabilities balance at the beginning of the period, as well as points that were earned during the period.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

(1)			The head leases associated with these subleases are classified as finance leases.

During the six months ended June 30, 2024, the Company acquired one incremental owned aircraft and took control of two aircraft through finance lease arrangements, one of which was subsequently subleased to the same unaffiliated airline to whom we subleased another aircraft during the year ended December 31, 2023. During the three months ended June 30, 2024, amendments were executed to extend the lease expiry terms for both subleased aircraft through the second and fourth quarters of 2025, respectively. Upon expiry of these subleases, both aircraft will be redelivered to the Company and are expected to be inducted into the Company's passenger fleet. Further, the Company purchased one aircraft previously classified as a

finance lease, which is now unencumbered. Of the 36 Owned aircraft and Owned Aircraft Held for Operating Lease as of June 30, 2024, 31 aircraft were financed and five aircraft were unencumbered.

During the six months ended June 30, 2023, the Company acquired five 737-900ERs that are currently on lease to an unaffiliated airline ("Owned Aircraft Held for Operating Lease"). The Owned Aircraft Held for Operating Lease are financed through a term loan arrangement. See Note 6 within Part II, Item 8 in our 2023 10-K for more information on this transaction. Additionally, during the six months ended June 30, 2023, the Company acquired an incremental aircraft and executed a lease amendment to purchase one aircraft at the end of its lease term. The lease amendment modified the classification of this lease from an operating lease to a finance lease and has an expiration date in fiscal year 2024.

Depreciation, amortization, and rent expense on aircraft are as follows:


		Three Months Ended June 30,				Six Months Ended June 30,
Aircraft Status	Expense Type	2024		2023		2024		2023
Owned	Depreciation	$	14,167	$	14,443	$	28,507	$	26,315

Operating Leased	Aircraft Rent (1)	—		779		—		2,259
		$	19,605	$	20,097	$	39,674	$	38,132


(1)			Aircraft Rent expense includes credits for the amortization of over-market liabilities established at the Acquisition Date.

BASIS OF PRESENTATION	Jun. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Sun Country Airlines Holdings, Inc. (together with its consolidated subsidiaries, "Sun Country" or the "Company") is the parent company of Sun Country, Inc., which is a certificated air carrier providing scheduled passenger service, air cargo service, charter air transportation and related services. The Company has prepared the unaudited Condensed Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (“GAAP”) and has included the accounts of Sun Country Airlines Holdings, Inc. and its subsidiaries. Certain information and footnote disclosures normally included in the audited annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for Form 10-Q. Therefore, the accompanying unaudited Condensed Consolidated Financial Statements of Sun Country Airlines Holdings, Inc. should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC ("2023 10-K"). Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited Condensed Consolidated Financial Statements for the interim periods presented. The Company reclassified certain prior period amounts to conform to the current period presentation. All material intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. Due to impacts from seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, the impact of macroeconomic conditions, and other factors, operating results for the six months ended June 30, 2024 are not necessarily indicative of operating results for other interim periods or for the full year ending December 31, 2024.

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS' EQUITY Equity Transactions Common Stock Repurchases The Company maintains a stock repurchase program, which has no expiration date and may be modified, suspended, or terminated by the Company's Board of Directors at any time. As of June 30, 2024, the Company did not have any remaining amount of Board authorization to repurchase shares of its Common Stock. During the six months ended June 30, 2024, the Company completed open market repurchases for 755,284 shares of its Common Stock at a total cost of $11,493, or an average price of $15.22 per share. During the six months ended June 30, 2023, the Company repurchased 1,166,751 shares of its Common Stock at a total cost of $22,249, or an average price of $19.07 per share. The repurchases were part of a secondary public offering of the Company's shares by the Apollo Stockholder, as well as open market purchases. The settlement of a $25,000 Accelerated Share Repurchase Program occurred during January 2023, upon which the Company received an additional 480,932 shares. Amazon Agreement On December 13, 2019, the Company signed a six-year contract with Amazon to provide cargo services under the ATSA. In connection with the ATSA, the Company issued warrants to Amazon to purchase an aggregate of up to 9,482,606 shares of common stock at an exercise price of approximately $15.17 per share. During the six months ended June 30, 2024 and 2023, 442,521 warrants vested in each respective period. As of June 30, 2024 and 2023, the cumulative vested warrants held by Amazon were 3,666,614 and 2,844,789, respectively. The exercise period of these warrants is through the eighth anniversary of the issue date. No incremental warrants were issued, nor was the original warrant agreement modified, upon the signing of the A&R ATSA. For more information on the A&R ATSA, see Note 2. Stock Compensation During the first quarter of 2024, the Company issued performance-based restricted stock units (“PRSUs”) to certain employees. The PRSUs are long-term incentive opportunities that represent the right to receive shares of the Company’s Common Stock based on the achievement of certain performance conditions over a three-year period. Potential payouts range from 50%-150% of a target level. The maximum number of shares that may be issued on the PRSU vesting date is 259,095. The Company recognizes PRSU stock compensation expense to the extent it is probable the performance condition(s) will be satisfied.

Debt Disclosure [Abstract]

DEBT

Credit Facilities

On February 10, 2021, the Company executed a five-year credit agreement (the “Credit Agreement”) with a group of lenders. The Credit Agreement includes a $25,000 Revolving Credit Facility (the "Revolving Credit Facility") and a $90,000 Delayed Draw Term Loan Facility (“DDTL”), which are collectively referred to as the “Credit Facilities.” The Credit Agreement includes financial covenants that require a minimum trailing 12-month EBITDAR of $87,700 and minimum liquidity, as defined within the Credit Agreement, of $30,000 at the close of any business day. The Company was in compliance with these covenants as of June 30, 2024.

Due to previous transactions which utilized the DDTL and the subsequent repayment, no amounts under the DDTL were available to the Company as of June 30, 2024. As of June 30, 2024, the Company had $24,393 of financing available through the Revolving Credit Facility, as $607 had been pledged to support letters of credit.

Long-term Debt

Term Loan Credit Facility

During the six months ended June 30, 2023, the Company executed a term loan credit facility with a face amount of $119,200 for the purpose of financing the five Owned Aircraft Held for Operating Lease. The loan is repaid monthly through March 2030. During the lease term, payments collected from the lessee are applied directly to the repayment of principal and interest on the term loan credit facility. The Owned Aircraft

Held for Operating Lease, as well as the related lease payments received from the lessee, are pledged as collateral.

The interest rate on the term loan credit facility is determined by using a base rate, which resets monthly, plus an applicable margin, and a fixed credit spread adjustment of 0.1%. The applicable margin during the lease term is fixed at 3.75%, and is subsequently reduced to 3.25% once the aircraft have been redelivered to the Company and a Loan-to-Value ("LTV") ratio calculation is completed at the end of the lease term. The interest rate in effect as of June 30, 2024 was 9.2%. To the extent that the LTV ratio exceeds 75% at the end of the lease term, a principal prepayment will be required in order to reduce the ratio to 75%. If at any point within 12 months of the end of the lease term for each respective aircraft the Company deems it probable that a principal prepayment will be required in order to reduce the LTV ratio to 75%, and such amount can be reasonably estimated, the estimated principal prepayment amount will be reclassified from Long-term Debt, net to Current Maturities of Long-term Debt, net on the Company's Condensed Consolidated Balance Sheets. In the event a principal prepayment is required, amounts received under the end of lease maintenance compensation clause will be applied towards any prepayment obligation. No amounts related to an estimated principal prepayment have been reclassified from Long-term Debt, net to Current Maturities of Long-term Debt, net on the Company's Condensed Consolidated Balance Sheets as of June 30, 2024.

During March 2022, the Company arranged for the issuance of Class A and Class B certificates (the "2022-1 EETC") in an aggregate face amount of $188,277 for the purpose of financing or refinancing 13 aircraft. The Company is required to make bi-annual principal and interest payments each March and September, through March 2031. These notes bear interest at an annual rate between 4.84% and 5.75%. The weighted average interest rate was 5.05% as of June 30, 2024.

In December 2019, the Company arranged for the issuance of Class A, Class B and Class C trust certificates Series 2019-1 (the “2019-1 EETC”), in an aggregate face amount of $248,587 for the purpose of financing or refinancing 13 aircraft, which was completed in 2020. The Company is required to make bi-annual principal and interest payments each June and December, through December 2027. These notes bear interest at an annual rate between 4.13% and 6.95%.

INCOME TAXES	6 Months Ended
INCOME TAXES	Jun. 30, 2024
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company's effective tax rate for the three and six months ended June 30, 2024 was 41.2% and 25.2%, respectively. The Company's effective tax rate for the three and six months ended June 30, 2023 was 22.9%. The effective tax rate represents a blend of federal and state taxes and includes the impact of certain nondeductible or nontaxable items. The increase in the effective tax rate during the three and six months ended June 30, 2024 was due to the impact of permanent stock compensation items on the effective rate. Tax Receivable Agreement The total Tax Receivable Agreement ("TRA") balance as of June 30, 2024 and December 31, 2023 was $97,694 and $101,044, of which $7,984 and $3,250 was current, respectively. The TRA liability is an estimate and actual amounts payable under the TRA could differ from this estimate. During the six months ended June 30, 2024 and 2023, the Company made payments of $3,350 and $2,425, respectively, to the pre-IPO stockholders (the “TRA holders”), which includes certain members of the Company's management and certain members of the Company's Board of Directors. The payment is included within Financing Activities on the Condensed Consolidated Statements of Cash Flows. Payments will be made in future periods as attributes that existed at the time of the IPO (the “Pre-IPO Tax Attributes”) are utilized.

BASIS OF PRESENTATION (Policies)	6 Months Ended
BASIS OF PRESENTATION (Policies)	Jun. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	The Company has prepared the unaudited Condensed Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (“GAAP”) and has included the accounts of Sun Country Airlines Holdings, Inc. and its subsidiaries. Certain information and footnote disclosures normally included in the audited annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for Form 10-Q. Therefore, the accompanying unaudited Condensed Consolidated Financial Statements of Sun Country Airlines Holdings, Inc. should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC ("2023 10-K"). Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited Condensed Consolidated Financial Statements for the interim periods presented. The Company reclassified certain prior period amounts to conform to the current period presentation. All material intercompany balances and transactions have been eliminated in consolidation.
Estimates and Assumptions	The preparation of financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
