if you read the above mike has booked with bulgaria air. Think when I looked for half term three adults (child over 12 is classed as an aduly) was £450 total.
Easy jet and ryan air are not the cheap air lines they used to be once you add everything on, plus drinks ect on board are a bit of a rip off. They are ok if you can get away with hand lug and book on line. but for ski trips that just not possible.
