I'm looking at European shorthaul flights. Would this work?
Fly out with aerlingus and fly back with ryanair.
Ryanair flies from my local airport to where I want to go, but not on Wednesdays (only Tuesdays and Saturdays). So I was thinking of going to a further away airport on Wednesday to fly out with aerlingus but then fly back again into my local airport with ryanair.
