If you are travelling from Luton on EasyJet then here is a tip for you. After security pass straight through the crowded main shopping area and head down towards gate 1-9. At the end of the corridors there is a quiet area with a coffee bar, and no people. Most EasyJet flights go from that end so when the flight is called you can quickly get to the required gate and be at the front of the queue.
A while back I realised I was not the only person, a few weeks on the trot I noticed a captain sat there staring at the departure times then when the gate was displayed he would jump up and walk in a hurry to the gate, he always beat me. One week I positioned my self near the exit and raced him to the gate it was a close thing. Turns out he flew for Whizz air and was from eastern Europe.
