There are lots of European LCCs, and the difference between them is enormous. Some of them even serve complimentary food (I'm sure AB do).
IMHO the defining feature of a LCC is that it's a point-to-point operation that will do its best to refuse/minimise liability for anything in case of irr ops. Even if I do appreciate a free and/or good meal, I happen to care more about the way whoever I am flying handles irr ops than the food quality on a 2-hour flight, that's why I don't fly them unless they are less than half price than conventional options (but this has only happened ONCE in the past 3 years!)
