Low-cost carrier easyJet has cancelled all flights to Sharm el-Sheikh in Egypt until January 6th.
Flights were originally halted after the UK government said the Sinai plane crash, which killed 224 people in October, may have been caused by a bomb.
The suspension has now been extended into the new year in an attempt to provide clarity for passengers, easyJet said.
A statement explained: “We are sorry for the inconvenience this will obviously cause, but we hope that being clear with all our customers at this point helps you to manage your plans with more certainty.”
Customers on affected flights could go to another destination, receive a refund or get a flight voucher for future travel, the airline added.
At the same time, British Airways has cancelled all flights from the UK to the Red Sea resort until December 17th, while Monarch had said it will not fly until December 19th.
Thomson and Thomas Cook presently plan to relaunch flights on December 9th and 10th respectively.
The Foreign Office, which advises against all but essential air travel to or from Sharm el-Sheikh, says there are currently no UK airlines operating flights to the resort.
