| Retirement and Other Benefit Plans | Retirement and Other Benefit Plans 401(k) Plans For the years ended December 31, 2025 and December 31, 2024, the Company had defined contribution retirement plans that covered substantially all employees. The Company contributed to these plans. The total expense incurred under all of the defined contribution plans for the years ended December 31, 2025 and December 31, 2024 was $1,563 and $4,349, respectively. The decrease in expense for the year ended December 31, 2025, when compared to the year ended December 31, 2024, was primarily due to the reduction in Air Wisconsin's workforce following the termination of the American capacity purchase agreement in April 2025. Supplemental Executive Savings Plan (SESP) The Company maintained the SESP for the benefit of certain executives. The SESP offered deferred compensation retirement benefits that would otherwise be subject to the compensation limits imposed by the Internal Revenue Code on Company contributions to the Air Wisconsin Airlines Savings Plan. As of December 31, 2025 the Company recorded Short-term restricted investments (SESP) of $1,127 and Deferred compensation liability (SESP) of $1,127. As of December 31, 2024 the Company recorded Long-term restricted investments of $3,797 and Long-term deferred compensation liability of $3,823 on its consolidated balance sheets. The SESP was terminated effective as of January 9, 2026, in connection with the Aviation Disposition.
