EasyJet, Thomson Airways and Thomas Cook Airlines have all extended their bans on flying to Sharm el Sheikh.

"We are keeping flights which are scheduled to operate from Saturday January 16, 2016 under review. The safety and security of our customers will continue to be our top priorities in any decisions we may make," the airline said in a statement.
"Customers who were due to travel on a cancelled flight claim a full refund or use the value of their ticket/holiday towards another flight/holiday on our network. They also have the option to rebook to an alternative date on a flight to Sharm el Sheikh."
At the moment government advice remains unclear, giving airlines little choice but to extend their cancellations.
