??? Have you been there in the evening or the morning ? Immigration in the morning can take up to 1/2 hour and security checks in the evening rush hour as well. Lounge is filled, no seats, everybody standing....a nightmare !
Ive flown at peak times out to Edinburgh - and yeah it was a bit crowded, but its such a nice small airport to arrive into - was off peak (just) mind you, but landing from Dusseldorf we went straight through passports, and luggage was waiting for us - straight onto the DLR (like the tube)... and onto a train within 15 minutes of landing.
Home within 1 hour of touching down using public transport. This would never happen from LHR or LGW! I love LCY!!
