An easyJet flight from London Gatwick to Belfast was delayed by over an hour after two members of the cabin crew were removed from the plane following a row.
The flight was due to take off at 2.45pm on Wednesday but was held up after what the airline confirmed was a "verbal disagreement".
TV presenter Dan Lobb was on board the plane and posted a series of messages about the incident.
He wrote: " This is a first. My easyJet flight has returned to gate because the cabin crew have had a tiff! One crew member being offloaded. Delayed."
Lobb described the situation as "unreal" with two crew members "being offloaded".
An airline spokesman said: "E asyJet can confirm that flight EZY835 from London Gatwick to Belfast returned to stand to replace two crew members following a verbal disagreement between them.
"The safety and welfare of our passengers and crew is easyJet's highest priority and in order to deliver this easyJet's cabin crew need to be able to work as a team.
"We would like to apologise for any inconvenience caused by the resulting delay."
