Belfast International Airport is disembarking passengers from nine aircraft as winds speeds reduce from 55 knots to 44 knots.
Flights from Edinburgh, Tenerife, Liverpool, Manchester, Birmingham, Newcastle, Glasgow, Gatwick and Bristol landed, but because of the high winds, it wasn’t immediately possible to manoeuvre aircraft access steps into place.
Two inbound flights, from Luton and Tenerife, diverted to Dublin.
The disruption will have a knock-on effect on scheduled departures to Gatwick, Glasgow, Bristol, Newcastle, Edinburgh, Liverpool and Manchester.
Earlier ground handling firm Swissport suspended operations as wind speeds exceed safety levels by some 7/10 knots.
A Belfast International Airport spokesperson said: “Airport staff and Swissport personnel are doing all they can to disembark passengers. We understand the frustration of passengers, and those waiting in Arrivals, but we must stress that the safety of passengers and our workers is our top priority and ask for their continuing patience.
“The high wind warning lasts until the early hours of Wednesday morning. Some airlines have cancelled flights, so we would ask passengers to please contact their airline for updates.”
