JetBlue withdrew four international destinations during 2026, ending flights to Antigua, Belize City, Bonaire and Tulum, all previously served from New York JFK. Bonaire ended in January, Tulum in March, Belize City in May and Antigua in September, with Antigua's route dating back to 2015 while the others launched in 2023 or 2024. At the same time, JetBlue added four international destinations in 2026 and saw Fort Lauderdale overtake JFK as its busiest airport, averaging 133 daily departures against 127 at JFK in the current winter schedule.

Sun Country stopped serving 25 destinations, mostly from its Minneapolis hub, with most last flights in August or September, and exited the Canadian market entirely after its last flights to Vancouver in August and Toronto in September. WestJet cut 15 destinations, including a complete exit from Cuba covering seven destinations, alongside cuts such as Halifax to Copenhagen and Madrid and Toronto to Glasgow. Alaska Airlines, by contrast, saw no airport cease service in 2026, according to schedule analysis; its three airport removals, Dallas Love, Nassau and Monterrey, all took place in 2025.

The four cases point in different directions rather than a single industry trend. JetBlue framed its changes as redeploying capacity toward Fort Lauderdale, where it reports its best financial returns, while Sun Country's winter schedule is down about 11.5% in flights and seats compared with 2025, according to Cirium data cited in the report. WestJet concentrated capacity back on domestic Canadian routes, and Alaska's network kept growing in October 2026, with Seattle remaining its most-served airport.
