well they say £0.79p, but when you add the charges on it's about £16
I've seen free flights before, but it's all about being in the right place at the right time ... and getting up extremely early. There was a flight from Bournemouth to Lyon for £1.50 ! But it was at 6:30am, which meant it would be impossible or very expensive to get to Bournemouth for that time in the morning.
Anyway, i digress ... where are you flying from mk ?
