Merger

The carrier reported full-year and fourth-quarter earnings this week.

Deal values Sun Country at about $1.5 billion as carriers move to combine operations.

The deal would form Mexico’s largest domestic carrier.

The ultra-low-cost carriers are again at the negotiating table after failed talks in 2022, 2024, and earlier this year.

Mesa stockholders approved the combination in a vote last week.

The deal is expected to close later this week.

The two airlines expect the deal to close later this month.

The carrier’s code and callsign will disappear by the end of this month.

The changes will come into full effect in April 2026.

Hawaiian Airlines CEO Joe Sprague will retire later this year and be succeeded by Diana Birkett Rakow, currently the senior vice president of public affairs and sustainability at Alaska Airlines.
