Aeromexico Faces Delta Seattle Cuts as Fuel Costs Jump
aeromexico is set to absorb more of the Seattle-to-Mexico traffic after Delta suspended flights from Seattle to Cancún, Los Cabos and Puerto Vallarta. The cuts start June 2, 2026, and leave Seattle passengers facing a narrower set of options through the autumn.
Delta tied the move to higher fuel costs linked to the conflict in Iran, saying global turbosina prices rose from around 2.50 dollars per gallon in February to 4.19 dollars in April 2026. For travelers, that means the Seattle leisure schedule is not just shrinking for a few days; one route disappears for more than five months, and another for about one month.
June 2 opens the first gap
Flights from Seattle to Cancún will not be available from June 2 to November 8, 2026. That is the longest cut in the schedule Delta announced, and it removes a direct option for summer and early-fall travel to one of the airline’s Mexico leisure markets.
Passenger rerouting will shift to routes from Salt Lake City, Atlanta, Los Ángeles or Ciudad de México with Aeroméxico. In practice, that means anyone who had planned around the Seattle pairing will need to look at a different departure city instead of waiting for the same itinerary to return.
October 6 hits Puerto Vallarta
Flights from Seattle to Puerto Vallarta will be suspended from October 6 to November 8, 2026. That narrower window still lands inside a busy travel period and leaves the route unavailable for roughly a month.
Delta also included Los Cabos in the suspension list, extending the pressure beyond one destination. The airline did not frame the move as a network redesign; it pointed squarely to the jump in fuel prices, using the figures from February and April to explain why the route economics changed so quickly.
December 2025 still matters
Andrés Conesa, Aeroméxico’s director general, said in December 2025 that there were no arguments for the Aeroméxico and Delta alliance to end. He also said the dispute was between the Mexican and United States governments over an alleged breach of the bilateral aviation agreement, not a dispute between the airlines themselves.
“Los argumentos del DOT (Departamento de Transporte de USA) no tienen que ver con temas nuestros o de Delta, sino que alegan que el Gobierno mexicano incumple con el acuerdo bilateral aéreo entre México y Estados Unidos, y ese es el debate que tienen entre los dos gobiernos, no es un tema ni nuestro ni de Delta. Con esta suspensión podemos seguir operando la alianza como la tenemos”
For travelers, that leaves one practical test: whether their Seattle-to-Mexico trip can be moved onto another city pair with Aeroméxico, or whether the direct route they wanted is gone until November 8. The route map changed first; the ticket options now have to follow.
