Easyjet are definitely the one for short-haul flights. We used to do Monarch when I was a bit younger for the slightly longer flights (3-4 hours to south of Spain) but then they started charging more and Easyjet came in to prominence and now obviously Monarch out of business.
I've flown Ryanair once and it was fucking disgusting. Plane looked like it hadn't been cleaned, you get much less space than Easyjet planes and obviously they charge you for hand luggage. They're both budget airlines which I can totally accept but the difference between the two is still quite significant.
Agreed. I've never flown business or first class even on long-haul. Best flight I've ever been on was when I went SA via Dubai a couple years ago; the plane wasn't full so we had a whole row to ourselves, therefore 3 seats to ourselves to lie down and make more room for ourselves. Plus drinks and food was complimentary so you obviously take the piss out of that. It somewhat helps (or prolongs) the inevitable jetlag when you land . That was on an Emirates flight and even for economy you still get treated so well.
Never had a hangover on a plane, mainly because I can't sleep on planes for a long time so the hangover can't set in! Dehydration and cold air is never a good combination, though. I always end up getting a dry throat because of the constanct supply of AC on-board.
