I wonder about no frills airlines, my colleague booked a flight for him and his wife yesterday from Aberdeen to Dublin with Ryanair. The price of the ticket was �0.00 (yes, really!), all he had to pay for was �20.00 air taxes for each of them, which is standard.
I wonder how on earth these airlines manage to keep themselves profitable.
no-frills airlines charge you for the frills. You'll pay extra for food, checking in at the airport, putting luggage in the hold, paying by credit card etc - your colleague should check the website before assuming �0 is all there will be. XL were more of an old-fashioned charter airline than a modern no-frills one, I think.
