American Airlines ( AAL) on Tuesday announced that it was expanding its services to Europe from the U.S., introducing new summer routes to Budapest and Prague from Philadelphia, and service to Venice from Chicago.

The additional routes will start on May 4, 2018, establishing Budapest and Prague as new destinations for the Fort Worth-based airline.

"Summer travel to Europe is very popular," said Vasu Raja, American's VP, Network & Schedule Planning. "These flights will conveniently connect customers from two very important hubs - Chicago and Philadelphia - to exciting markets across the Atlantic."

This summer, the carrier began service to Amsterdam and Rome from Dallas/Fort Worth, and to Barcelona from Chicago, further extending its European services.

Shares of the carrier were climbing higher during mid-morning trading on Wednesday.
