First time Iceland Air. Ridiculously small amount of leg room, flight was hotter than hades and people kept requesting for cooler air that never came. You pay for everything, no food of any kind unless you pay which I've never seen on a flight of this length. Just seemed like they are cheap as possible about everything. Won't fly with them again if I can avoid it.
