OK, not as good as the 1p one way deals that were around earlier in the week. However if you missed out on them - there's a load of £9.99 flights available (just to be clear, you do not pay taxes or any extras unless you choose other flights not included in the deal).
All you have to do is select a £9.99 flight from the list (on the left of the screen you can choose your starting airport from a drop-down list "click here for more departing airports" - it then tells you which destinations are included). To cancel their insurance charges click "no travel insurance required" from the drop-down menu that starts off filled with "please select a country of residence". Select 0 bags (you can take a 10kg bag with you for free). Pay by Visa Electron (got mine through the Co-operative bank), chek-in online and print off your boarding slip and Robert is your father's brother.
If your selected flight comes up with all the taxes - choose a different flight on a different day - there's loads to choose from (1 million seats).
But you CAN get return flights round Europe for just under £20.
