Are your prices for a one-way or return flight?

To give you greater flexibility, the stated TUIfly fares refer to the one-way flight only. Passengers who want to book a return flight show this when entering the booking, and will then see the corresponding TUIfly fare for each one-way flight. TUIfly fares are exclusive of taxes and duties, which are charged according to flight destination and flight route. These taxes and duties are the sums which TUIfly.com has to pay to local authorities, airports and insurance companies.
