Having just flown with Jet2 to Madeira and back we were quite impressed and will be using them again. Good service as budget airlines go, and they're obviously trusted on Madeira's 'aircraft carrier' airport. Except their slightly irritating jingle which sounds ripped off a Floyd(?) song, but once you're buckled up you get a decent service. Used Easyjet in the past and would still do so, Ryanair avoid like the plague.
