I got a voucher for Ryanair. Decided to use it. This meant phoning Ryanair on their premium number to do the booking. 33 cents per minute. The whole proceedure took 18 minutes. I kid u not!. There were some flights in sterling. The prices charged were much higher that those that came up on the Ryanair site minutes before. For example one flight I costed at €65.00 became €85.00.
