As frustrating as it can be for passengers, airlines are entitled to make such diversions if they can solve an operational issue, the Independent stated.
In the case of Tui Airlines, the flight dropped off equipment required for a TOM529 aircraft which had a technical issue, a spokesperson told the news outlet.
The spokesperson apologised for the “inconvenience” and said passengers were given a free drink on board the flight and told they could claim EU261 compensation.
If a passenger’s flight arrives three or more hours past its scheduled arrival time, they are entitled to £350 (NZ$630) under certain circumstances under European Regulation EU261.
However, the flights must be operated by an EU airline or departing from an EU airport.
