American will use Boeing 787-8 Dreamliners for all the new flights except for Zurich to Dallas, which will be flown by Boeing 777-200s. American is adding seasonal service to Budapest, Prague and Buenos Aires for next summer. Many of American's summer routes were discontinued because of the Covid-19 pandemic.

With Prague and Budapest service from Philadelphia, the airline is betting on customers flying into one city and out of the other for Danube River cruises.

Tickets to the resurrected Budapest and Prague routes go on sale Monday, Aug. 11 through the American Airlines website and mobile app. Follow Kristin & PhillyVoice on Twitter: @kristin_hunt | @thePhillyVoice Like us on Facebook: PhillyVoice Have a news tip? Let us know.
