Monarch has cancelled flights to Sharm el-Sheikh airport until late January.
The cancellation period has been extended from January 6 to January 24 as the Foreign and Commonwealth Office (FCO) and the Department for Transport (DfT) continue to advise against all but essential air travel to the destination.
“Monarch has taken this proactive decision to allow our customers to make alternative holiday plans as soon as possible,” said the company in a statement.
Customers affected by the change are entitled to change their booking to a later date or rebook to another destination on the Monarch network.
Affected travellers can also request a credit note towards future travel or a refund.
For customers looking for an alternative destination Monarch has additional flights to mainland Spain, Faro, Gibraltar and Tenerife.
Monarch continues to operate to the Red Sea resorts of Hurghada and Eilat as well as Cyprus, the Canary islands, Agadir and Madeira this winter.
UK airlines and operators had to fly more than 16,500 holidaymakers home following the downing of the Russian Metrojet Airbus which killed all 224 people on board and subsequent security issues at the Red Sea resort airport.
“The safety and security of our passengers will always remain our number one priority and whilst this ongoing situation is beyond our control, Monarch would like to apologise to all affected customers for the inconvenience that it has caused,” the statement continued.
