American Airlines is stepping up frequency between Heathrow and Dallas/Fort Worth this summer.

The airline is to add a fourth daily flight six times a week from June 14. There will be five daily frequencies between the Texas hub and London when combined with transatlantic business partner British Airways.

American will use a Boeing 767-300 on the additional service with 219 seats including 28 in business class. The expansion comes as the carrier marks its 30th anniversary of flights between DFW and London with the introduction of a daily service in 1982.

The service was increased to three daily flights and was moved to Heathrow in 2008.

UK and Ireland sales director Graham Bell said. “This additional service provides even more links from London Heathrow to our major hub in Dallas as we now serve Dallas/Fort Worth up to five-times daily in co-operation with our joint business partners at British Airways.

“It is a double celebration as we reach our 30th anniversary on this route and demonstrates the ongoing success and attraction of Dallas/Fort Worth as a global hub and gateway to Texas.”
