PASSENGERS heading out of the George Best Belfast City Airport were delayed on Tuesday morning.
The 7 am flight from Belfast to Leeds was still on the runway at 9 am after the overnight snow.
Those on board have been told by cabin crew that the de-icer machine had run out of fluid.
One business passenger jokingly told Belfast Daily: “I think one of the maintenance men has nipped down to the garage to get more de-icer fluid!!!!
“We have been sitting on the runway since 7 am. We still don’t know what time we will be taking off at.
“It is ridiculous. One flurry of snow and the airport can’t function properly.
“Some of the passengers got so fed up that they have got off as there is still no sign of of us moving.
“Because of the delay people have missed business appointments.”
The Belfast to Leeds flight eventually took off and landed just after 11.30 am.
Added the passenger: “We landed safely. But it was a mad flight. It felt like we flew upside most of the way.”
