American Airlines is ramping up the domestic summer schedule to near pre-pandemic levels

American Airlines is expanding its summer schedule in a bet that the revival in travel demand will continue as more people are vaccinated.

This summer, American plans to operate more than 90% of the domestic and 80% of the international schedules during the 2019 peak season, adding 150 new routes for the peak season. American said capacity was down more than 43% in the first quarter compared to the same period of 2019.

Airlines eager to accommodate a boom in travel are weighing up how much capacity they can deploy this summer. Demand has soared as more people have been vaccinated against Covid-19, travel restrictions are simplified, and more attractions, such as Disneyland, are preparing to reopen. Airline executives will begin informing investors about their strategies this week, when Delta launches quarterly reporting on Thursday.

“During the pandemic, it has been our trademark to create a schedule based on what customers tell us they want and need,” said Brian Znotins, American vice president of network planning in a release. “And today they tell us they would like to travel again.”

With international travel still depressing, American plans to use some of its Boeing 777s widebody planes on domestic flights to New York and Los Angeles from its Miami hub. Americans and competitors such as United and Delta have added flights to destinations with outdoor attractions such as beaches and mountains, as travelers seek a vacation where they can be physically distanced from others.
