Update 5/13/26: Acquisition has been completed.
Allegiant & Sun Country have announced plans to merge in a $1.5 billion deal. Allegiant will acquire Sun Country in a cash and stock transaction with an implied value of $18.89 per Sun Country share (0.1557 shares of Allegiant common stock and $4.1 in cash).
The new combined airline will operate under the Allegiant name. The deal still requires regulatory approval, the DoJ last blocked JetBlue’s acqusition of Spirit Airlines in 2024 but that was under the Biden presidency.
Sun Country does offer a cobranded card with Sychrony and Allegiant offers a cobranded card with Bank of America but neither offer particularly outsized value.
