But according to Jan Lindvist at the Swedish airport operator LFV, travellers from Sweden were relatively unaffected.
“Just one British Airways flight in both directions was cancelled and all SAS flights were able to depart, albeit with delays. It was quite a good traffic day,” he told The Local.
British Airways’ 11.45am service from Stockholm Arlanda to Heathrow was cancelled, while SAS flights to London were delayed by up to three hours.
British Airways could only confirm that UK domestic flights would not be operating until midday, while shorthaul flights to Brussels and Paris would not resume until Sunday morning. All longhaul flights operated as normal on Friday.
In a statement on its web site, the airline said that it was planning to operate its full Christmas Eve schedule.
Jan Lindqvist said that LFV had no information about potential cancellations on Saturday or Sunday.
“Hopefully Saturday will be a normal day for air traffic but Sunday, Christmas Eve, is a very low traffic day for us anyway,” he said.
