That's interesting F3G. I took a quick look at the Delay and Cancellation bits of the T&C of Easyjet, Ryanair and BA.
Both BA and Ryanair are essentially the same i.e. we will give you what the law makes us, and nothing more. This is as one might expect.
Easyjet however do appear to provide more than what the law requires, and they put it in writing too! It looks like they will feed and accomodate you if the delay is not their fault. They also don't appear to have a clause which says the T&C which apply are those which are in place at the time of flight, not time of booking - an underhand move that another airlines has hit their passengers with recently. So good for Easyjet.
