A British Airways flight supposed to be flying from London to Düsseldorf in Germany landed in Edinburgh by mistake on Sunday after a flight paperwork error.
Passengers were made aware of the mistake when a "welcome to Edinburgh" announcement was made, the BBC reported.
Sophie Cooke, a 24-year-old management consultant, said when the pilot first made the announcement that the plane was about to land in Edinburgh everyone assumed it was a joke. She asked the cabin crew if they were serious.
The pilot then asked passengers to raise their hands if they wanted to go to Düsseldorf.
Everyone raised their hands.
The plane, which started at London's City Airport, was then redirected and landed in Düsseldorf. German firm WDL Aviation ran the BA flight through a leasing deal.
BA said it was working with WDL to find out why it filed the wrong flight plan.
"We have apologised to customers for this interruption to their journey and will be contacting them all individually," BA said in a statement.
WDL said it was "working closely with the authorities to investigate how the obviously unfortunate mix-up of flight schedules could occur".
