Great experience, and best in our Europe trip, comparing Easy Jet, Ryan Air, and vueling when having cabin bag in the equation. Plenty of leg room, as much as the additional paid leg room seats on the other flights we had, boarding from back as well as front of plane was a bonus. No waiting around on the tarmac in full sun (thanks RA), great boarding! Good crew, and a few free rows of seats.
