A London bound passenger jet diverted to Shannon Airport this morning after fumes were detected on board.
British Airways flight 2156 was en route from Antigua in the Caribbean to Gatwick Airport when the crew reported a problem.
There were 239 passengers crew on board the Boeing 777-200 jet which was south of Cork when the odour was detected by passengers and cabin crew members.
The crew confirmed however there was no visible evidence of smoke or fire.
The pilot advised air traffic controllers at Shannon of their situation and requested permission to divert and land there.
Emergency services were standing by at Shannon for the flight when it landed safely at 8.57am.
The passengers have been taken to the terminal while engineers investigate the issue.
Arrangements are being made to get the passengers to their destination but they are expected to continue their journey this afternoon.
A British Airways spokesman said: “We apologise to customers for the diversion of the BA2156 Antigua to Gatwick service to Shannon. This was due to a minor technical fault. We are providing a replacement aircraft to fly customers back to Gatwick later today. Safety is always our first priority.”
