LHR flights being reduced to 3 to save night stopping crew in london and because of better slots for the winter
Dantheflyboy- Aer Lingus are not reducing the frequency on the BFS LHR route for the winter to save on night stopping crew, this is a traditional pattern that was in place for years for the Shannon flights to Heathrow. Aer Lingus have additional slots in the summer,hence a fourth rotation.
They would retain the 4 daily if they were allowed in the winter too. THe summer will be a early LHR departure and in Winter the first flight on the route will be from Belfast. However they have managed I believe to bring back the departure time by a few mins to 0730.
