That went better than expected. Arrived at T5 at 7.30. Ten minutes to bag drop at Club desks and then fifteen minutes through security. Fast Track security was open but a fairly long queue so went through regular security.

My wife also commented the security staff seemed more cheerful and friendly - but hardly surprising given the novelty factor and no doubt decent overtime rates!

Was a queue for the lounge but this was because for some reason at least a dozen people were trying to get in with their Priority Pass or Platinum Amex cards.
