LGKR
i suppose its luck whether you run into trouble with any of them, however my experiences with both, EZY from LGW to Zurich and ryanair up to edinburgh, ryanair was running quite late, but not uncommen in the airline industry!
well i suppose i find easyjet better because it flys out of gatwick, also from what ive read about ryanairs ceo, micheal o leary, his policy is one of its a cheap flight, so you cant expect any real help from the airline if they go wrong.
