An aircraft carrying delegates home to Gatwick from the Advantage conference in Turkey was forced to make an emergency landing in Izmir.
The Pegasus Airlines aircraft took off at 7am local time from Bodrum on Monday morning.
The enforced landing at Izmir at 9am was described by the airline as precautionary due to an unspecified technical problem.
Reports suggest the issue may have been related to the cabin pressure inside the aircraft.
Passengers were transferred to another Pegasus aircraft and the flight took off at 10.12am.
The flight landed at Gatwick almost three hours later than originally scheduled, at 12.05 local time.
