i also checked the fare, if you can get it for €9 the one way the return is most probably more expensive.
Above that, when you look things up on the basiqair website for the surcharges you will find some charges that make no sense to me at all.
if you want to fly to london the same day but on Easyjet, the fare that EZY gives you is around €25-30 per leg but EZY doesn't charge the things that Basiq does.
anyway, the total amount for a return on basiqair would be €75 and on EZY it was €72
