Delta Airlines to operate flight from PHL to London Heathrow

[mfs NJT459]

Consider they already have a seasonal flight from Philly to Paris, this new one is part of a joint venture with Virgin Atlantic, and its part of the US Airways-American merger and a settlement with the US Justice Department for PHL

 

So it will be US Air, British Air, and Delta
