Just checked Mytravellite website. At the moment you can get a flight out (from Birmingham) Thursday morning (10.05) for £1 + £9 tax. Return flights on Saturday lunch time £9 or late night £1.03 + £8.97 tax. So you can fly out Thursday morning, return late Saturday night for £20 including tax. I'm seriously thinking about it. Birmingham is probably the most convenient airport for me too, so that's an added advantage.
