There is some good news for anyone travelling through Heathrow Terminal 5 in the next few weeks.
The Plaza Premium lounge, which is by far the best of the two independent lounges in the terminal, has just reopened. The website states opening hours of 6am to 5pm.
The only snag is that the lounge does not accept Priority Pass or Lounge Club cards. It does accept DragonPass.
It also accepts American Express Platinum charge cards. Whilst the Priority Pass that comes with Platinum will not get you in, you WILL get in by showing The Platinum Card itself. This is due to a separate global deal that Amex has with Plaza Premium.
If you don’t have any of these cards, you can also book a slot for cash via the Plaza Premium website here.
