But even STN is horrible;
Flew once so far and booked again with Eurowings. Connection to the centre seems to be at least equally conveniant compared to LHR with Heathrow Express and changing to Victoria Line at Tottenham Hull.
@ legroom: I agree in general but sometimes it makes sense to fly for 1 hour or so with small legroom and save some $$. All a question of value and capacity for suffering
