I am a regular traveller from Luton airport other London and international airports. Luton is the worst. Security queues have always been very bad at peak times and now road traffic queues are appalling. Once in the terminal the queue for security stretched out of the security hall down the stairs and into the main concourse. At security my bag was selected for swabbing but due to inadequate supplies/equipment this was delayed another 10 mins. I left security at 6.40 too late for my flight. The Servisair representative who escorted me out of the secure area complained that it took them 55 mins to get from the staff car park to the terminal in the staff bus due to the same traffic problems. Until they can manage the traffic they should reduce the number of flights at peak times.
