I have a couple of airports that I like in the UK….
London Heathrow, (especially T1). I travelled so many times when going to Cyprus that I began to know its wereabouts relatively well (until the next time they make a change inside the departure lounge)
London Stansted, because it is a relatively new airport with a nice terminal building, easy accessible and passenger friendly. I am travelling from there on 11th July to go to Cyprus for three weeks.
Birmingham Airports because it is again passenger friendly airport and easily accessible.
