In peak times and in the summer season, we hire extra aircraft from our partner airlines to make sure that everyone can travel with TUI. So we can offer you more choice of destinations and travel times, we sell our holidays with flights offered by other airlines, too. We call these our non-TUI airlines.TUI partner airlinesMost flights booked with us will be operated by TUI Airways. However, on occasions, we may lease aircraft from other airlines so we can run more smoothly in busy periods. When this happens, you’ll see the name of the airline when you book your holiday. Our TUI partner airlines include Albastar, Aegean, BA CityFlyer and Freebird.Most of these flights will operate with TUI cabin crew and offer full TUI service. Where the TUI partner operates with their own cabin crew, they’ll provide an equivalent service to our own.Our TUI partner airlines are carefully selected to make sure you receive the same high TUI standards of service, and they all meet strict Civil Aviation Authority (CAA) or EU Aviation Safety Agency (EASA) standards. Should we need to change your aircraft to a TUI partner airline after you’ve booked, we’ll let you know as soon as possible. For more information on our TUI partner airlines, please see our partner airline page.Non-TUI airlinesSo that we can offer you more choice of destinations and travel times, we also offer flights from other non-TUI airlines. If you fly with one of our non-TUI airlines, your flight will be operated by another airline. The cabin crew and service are in the hands of this company, meaning that when you add your passenger information, check in or add extras to your flight, you’ll need to manage this through the partner airline’s website or app. You can find out more on our partner airlines page.
