relax enjoy your trip, all the above replies are helpfull, I understand what you say, it is not the rules that are causing the annoyance, it is the fact you were not advised of the extra costs, this is what also gets me, when I think I have been "tricked by the price" anyhow, be rest assured that it appears that nowadays all airlines have the same tricks, I have used both Ryanair and Easy jet regulary and found no problems,If in doubt I have booked the check in bag online, to prevent me stressing at the airport about weight, but one point I would like to stress is to make sure that you print the boarding passes before going to the airport, I got caught out last month, and tried to do it before I went to the airport, but got caught out by the 2 hour before travel rule, and found myself with a costly bill at the airport,
