I was initially worried I couldn't book seats - they changed the dates 3 times. I contacted them online on their live webchat, it's easy to find on tc holidays then they'll give you the right link for flights. Seems to me, now that I've managed to book the seats (and a day earlier than they said) that they are maximising what they have before firming things up, by that I mean they are looking at bookings and waiting to assign the appropriate plane to them. We're booked to go on a 3+3 configuration, but coming back, at the end of the bank holiday week at the beginning of June, we've got a 2+4+2, so a much bigger plane.
