How much added benefit is bulk cargo on the B757? It's not palletised alas.
American have a terrible hard product on the B757, that's part of the reason BHX-JFK was dropped, LHR-JFK had a much better offering. Let's park the wee GLA vs EDI stuff? Take it to PM
I could see United using B767s at EDI, the B757s are getting on a bit, er much like the older B767s !
