When Easyjet offered Liverpool-Luton, it was popular, in fact I used it quite a bit and couldnt always get on, sometimes also fares were quite high (as the flight was nearly full) however I think many people from the Northwest don’t think of Luton as a London airport, and im not sure if many business travellers liked it. The train from Luton Airport Parkway in the mornings is packed, after getting up at the crack of dawn to catch an 0600 from Liverpool, you really want a more relaxing transfer into central London. I used the 757 Greenline bus a few times which was quite comfortable, but then you are on the M1 !

VLM offers a much better service to London from Liverpool now, and their on-time performance is good, Easyjets on LPL-LTN was debatable. I also remember they were moaning about landing charge increases at Luton at the time.
