Manchester Airport
Passed through Terminal 1 recently for a flight at 08.00 which is smack bang in the middle of the morning peak period.
Check-in was quick and efficient and absolutely no delays at security.
Sure, the Terminal is not pretty at the moment but it is FUNCTIONAL. There was not one single flight showing a delay to the departure time.
The more observant passenger will not have failed to notice several huge signs saying 'THIS TERMINAL IS CURRENTLY UNDER RE-DEVELOPMENT - COMPLETION DUE SPRING 2009. We apologise for any inconvenience.'
Having now seen the extent of the re-development, I personally feel that it has taken some exceptionally good planning to maintain the throughput of passengers and prevent flight delays due to airport services during the re-development phase.
