Yes, Ryan Air are at it again. Not just charging for food on board but on our recent flight (Gran Canaria to Bristol, 31 May 2013) doing a slight of hand to over charge.
Despite the in-flight mag giving very specific prices (and the cabin staff pushing this a 'see what is on offer'), they are trying to charge over this at the point of sale - because 'WE HAVNT UPDATED THE MAGAZINE WITH THE NEW PRICES YET'.
Okay, they backed down when I reminded them ts was actually FRAUD - you cant advertise at one price and charge another - there were plenty of people on the flight who didnt spot this and therefore paid inflated prices.
BE CAREFUL - check the prices, do your own maths and question every bill.
