Well, the truth is that I actually need to be in Devon (Totnes), so this was an excuse to earn a few TPs and sit in the lounge... NQY was simply the closest airport to Totnes that BA supposedly serves. It would have then been a matter of renting a car and driving (under 2 hours, I think)...
Otherwise it's a very long train ride with a change from London.

Oh well... I tried looking for PAR-NQY but that becomes complicated: cheapest option was ORY-LHR-LGW-NQY if I remember correctly, and it was >EUR300 and too much of a hassle. Shame...
