I flew from Gatwick to Krakow with Easyjet in October last year and can heartily recommend them. I paid extra to take a second bag on board with me as I prefer to have electrical items such as my Kindle and camera close to hand, apart from which the rucksack I use to carry them in would not fit in my small suitcase. Check in was smooth and easy, as was boarding. Officially I was supposed to have so-called speedy boarding, but all this meant in practise was that I was allowed to board the bus that took us to the plane first. It doesn't matter of course anyway, as the plane isn't going to go anywhere until everyone is on board.
It was only a short flight of around 2 hours, but even so, as it was timed to arrive at lunch time and with the ongoing journey into Krakow itself, you still have to eat. In common with most airlines Easyjet do not offer much in the way of gluten free food - I think the choice was either tomato soup or maybe a bag of crisps. Having anticipated such a scenario I had of course taken my own, but it would be so nice just once to find an airline that understood that those with such dietary needs would really like to have the same choice as everyone else - and yes, that choice should also be vegetarian, as everyone can eat this. I live in hope that one day an airline somewhere will take this quite literally on board.
This is really the only gripe. Other than that Easyjet are very efficient and well priced, and I would definitely fly with them again.
