Consumer law and airline prices
Many airlines offer flights that appear to cost just a few euros but end up costing far more, thanks to the airline's "handling fee" for credit card transactions, airport charges and government taxes.
So always be wary of what appears at first to be a very cheap flight, because it might not be quite so cheap in the end.
In more recent times airlines have added extra charges that you might not be fully aware of until you arrive at the airport, such as charges for checked-in baggage.
Information about any of these charges made by the airline, from any booking charges to baggage fees, must be notified to you in advance of completing your booking.
'Departure fees'
Some regional airports also charge passengers a "development fee" (sometimes called a "departure fee"), payable at the airport before they can fly. But as this particular fee has nothing to do with the airline, it is not obliged to tell you about it.
There are specific rules about how air fares should be advertised on radio, television and in print. You should be told whether a flight's price is only applicable between certain dates or times.
Booking and charges
Whenever you book airline tickets, whether online or from a travel agent's office, the best advice is to keep a sharp eye on all the taxes, fees and other charges which may be added as you progress through the booking.
If you are ordering tickets online, sometimes the booking form also "assumes" that you want to take out travel insurance, so you have to change the form to indicate "No Insurance" if you don't want any.
If you don't like the added cost, don't complete the order.
