The main reason Luton has prospered is Eastern Europe with many passengers having no choice but to fly from Luton
I agree and this is in no way a reacist comment but I can't help but think I might be happier with LTN as my local airport if we didn't have Wizzair. Others would fly to the places I might like to go (Prague. Budapest etc) - I am unlikely to go to most of their destinations.
But in truth I am unlikely to fly Thomson either- I would fly Easy to most of their destinations where there is higher frequency and self plan the holiday. Have only used Easy and Ryanair in the last 10 years.
