Can't see this posted.
Note that some of these deals must have ran out (yet are still advertised - grr) I wanted Liverpool to Valencia, but none available. Liverpool to Stockholm still available - Oslo not, for example.
Also, some £3 fares add £6 online check-in, some don't. £6 returns are out there... if only I lived in London for access to so many routes :(
We all know about how far the airports can be, and card and luggage fees, but these can be avoided and bargains found.
*When I say 'all in' I mean taxes, fees and charges. Not luggage, card payment fees and the like.
