No ones mentioned Thomas Cook, they commence flights to Boston in a few weeks and to San Francisco in May 2017.
It will be interesting to see how this works out for both Virgin Atlantic and Thomas Cook.
Delta do not really have much of presence at either BOS or SFO to offer connections off the Virgin flights, as these are not focus city or hubs for the airline. So both airlines will be relying on O&D passengers.
Will there really be enough of a market between Manchester and these cities, for both airlines to operate successfully with full flights?
