All of the flights represent seasonal summer service and will fly June-September, using Boeing 767 aircraft with lie-flat seating in business class.

The Dubrovnik flights will operate three times weekly, while the Berlin and Bologna flights will operate four times weekly.

American added seasonal daily nonstops from Philadelphia to Edinburgh, Scotland in April. The airline also commenced service on June 6 from Dallas-Fort Worth International Airport to Dublin and Munich.
