Gatwick and Luton airports were closed yesterday, while heavy snow was expected at Stansted overnight leading to fears of more disruption for travellers.
Bristol Airport re-opened yesterday afternoon but there were significant delays and some cancellations following the airport closure on Sunday night.
Further afield, Madrid Airport was last night experiencing delays as a result of bad weather and at Paris Charles De Gaulle, weather disruption was further exacerbated by the French Aviation Authorities imposing flight restrictions following the backlog of delays.
The chaos comes just days after travellers breathed a sigh of relief as British Airways won an injunction to stop cabin crew staging a walkout.
Easyjet, which operates flights to and from Belfast airports to the affected airports, has advised passengers to consult the flight disruption section of its website before leaving home.
“If their flight has been cancelled the airline requests passengers do not go to the airport,” a spokeswoman said.
She said that passengers can apply for a refund or transfer but warned that there is little availability over the next few days so passengers whose flights have been cancelled may not be able to transfer to flights departing over the coming days.
The freezing snap is expected to continue across Northern Ireland in coming days, and a Met Office spokesman predicted a bright but cold start to Christmas Day.
