Airline Seat Cuts Threaten US Connections to Mexico’s Caribbean Coast

Cancún, Quintana Roo — Airlines will offer 435,691 fewer seats and about 2,600 fewer flights between the United States and Mexico’s Caribbean coast in the final quarter of 2026, according to market monitoring by the Sustainable Tourism Advanced Research Center (STARC) at Universidad Anáhuac Cancún.

The analysis found seat capacity down 12.8% and scheduled flight operations down 13.3% for October, November and December. The tighter capacity could push fares higher on routes serving Cancún, Cozumel and Tulum.

Spirit and American Lead the Reductions

Spirit Airlines accounts for the largest cut, with 198,880 fewer seats than in the same period of 2025. In the schedule STARC reviewed, the carrier shows zero seats for the quarter, effectively removing all of its programmed capacity from the comparison.

American Airlines follows with 115,790 fewer seats. Its October-December schedule totals 829,429 seats, a 12.3% decline from 2025, while United Airlines has programmed 735,237 seats, a drop of 7.4%.

The steepest reductions reported by the research center are:

• Spirit Airlines: 198,880 fewer seats
• American Airlines: 115,790 fewer seats
• JetBlue: 76,532 fewer seats
• United Airlines: 59,155 fewer seats
• Other carriers combined: 14,866 fewer seats

Some Carriers Add Capacity

A handful of airlines are bucking the trend. Southwest Airlines leads the increases with 15,944 additional seats, followed by Breeze Airways with 10,412 and Frontier Airlines with 4,090.

Southwest’s October-December schedule reaches 133,969 seats, an 8.6% increase over the same period last year. Those gains, however, do not offset the cuts at Spirit and American.

The outlook poses a challenge for Quintana Roo’s tourism destinations, which rely heavily on air arrivals from the United States. Fewer available seats can limit travel options and raise costs for passengers, though the final impact will depend on demand, fares and any adjustments airlines make during the quarter.
