Passengers booked to fly from Gatwick to Florence were told their plane departed without them due to delays that have hit airports across the UK.
Vueling flight VY6209, which can carry up to 144 passengers, was due to depart at 8.20 pm on Monday.
However, the aircraft left Gatwick airport two hours late but with no customers on board.
The incident is one of many as UK airports struggle with travel demand during the half-term holidays. Passengers have faced cancelled flights, delayed departures and hours in queues due to staff shortages from airlines and airports.
A passenger from the Vueling flight told the PA news agency they queued more than four hours to check their luggage.
