I completely agree with farmer jo. Luton is dire. It's an abomination of an airport with a couple
of controllers (one male, one female) who are incompetent, pedantic immigration officials and the most aggressive and objectionable security officials outside Russia.
The best in the UK? FARNBOROUGH. A quality experience from start to finish. Worth every penny.
Wish I were still based there instead of at the Bedfordshire bumhole.
