easyjet pay less because: when they first went to Luton the airport was dead on it's knees and desperate for business. LLA offered them a 5 year start up deal at the £5 rate. That deal is now over, easyjet are I believe, negotiating for a new rate. They believe they should have a preferential rate owing to the fact that they provide Luton with more than 80% of it's work. Seems fair to me, open markets etc.
