CATIII-NDB, as you're so obviously disenchanted with Luton why not try using Birmingham, Coventry, East Midlands, Gatwick, Heathrow or Stansted? In fact, any airport other than Luton which so obviously, raises your blood pressure...
PS. If your obvious stress causes you to suffer a heart attack in Luton's terminal, don't worry - the use of the defibrilators there is free of charge.
