Having recently travelled through T3 I have to say it's the biggest sh!t hole excuse for an airport terminal.........and I think that's being quite charitable.
What the hell were they thinking with the layout of check-in? security? shopping? On a Friday night it is a nightmare. Took me 30 mins to get through security.
T4 should be the model for terminals in the UK...........but even that's descending into chaos as more and more shops get crammed in!
