Have just had my first T5 experience flying to ABZ. Have to say that I am very impressed with the new place. Had no wait to check my case in, no delay and very efficient through security. Lots of room in the departures area and great views! Once any remaining glitches are sorted I really think it will make travelling through Heathrow a much more pleasant experience.
(and didn't see 1 cancelled flight on the boards!!!)
