There are few transatlantic markets that have seen such considerable growth as the corridor between Spain and the United States of America in the past year. According to present scheduling data made available by Cirium , an aviation analytics company, 1,724 flights are scheduled on routes between these two nations in December 2025. This represents a 16% year-on-year increase compared to December 2024's figure of 1,486.

As such, seat capacity has also risen, albeit by a slightly smaller margin of 14.9%. This reflects the fact that some of the additional flights are operated by smaller aircraft, with Iberia's increased deployment of the Airbus A321XLR being a key factor on this front.
