Southwest Airlines confirmed its agreement with Babcock & Brown Aircraft Management (BBAM) to sell 36 Boeing 737-800 aircraft, which will be leased back to the airline through BBAM’s subsidiary, Incline Aviation III, for a duration of 26 to 37 months. Tammy Romo, Executive Vice President and CFO of Southwest Airlines, stated, “This transaction is part of our ‘Southwest. Even Better.’ transformational plan. By monetizing surplus value from our Boeing 737 fleet, we are generating significant cash to drive fleet modernization and offset capital expenditures.”

  • Leasing Duration: 26 to 37 months

United Airlines’ Purchase of Embraer E175s

In parallel, United Airlines has engaged in a sale-leaseback agreement with Mesa Airlines, a regional operator, to acquire 18 Embraer E175 aircraft. According to the SEC filing, the transaction was initiated with the sale of eight aircraft, finalized on December 31, 2024, while the remaining ten are anticipated to close by February 1, 2025.

• Financial Implications:
  • Total Proceeds: Estimated at $229.1 million
  • Debt Repayment for Mesa: $142.4 million from the proceeds
