Compton3bravo, true that is a lot of additional capacity but having endured the 'Luton experience' I've heard so much about for myself last week I could see them attracting a fair number of people who might otherwise have used EZY/MON/TOM from LTN.
The impact on SEN will be interesting - though I personally would rather use SEN given the choice. On the one hand it will also compete with SEN's market, on the other EZY coming under pressure at STN could see them move an aircraft or two over.
