Monarch has extended the cancellation of flights to Sharm el Sheikh for another three weeks in the wake of the Russian airliner bombing in October.
Flights were already cancelled up to January 6, but this has now been extended until January 24.
Many other airlines have already cancelled flights until next year.
The advice from both the Foreign Office remains unchanged and advises customers against all but essential air travel to Sharm El Sheikh Airport.
Monarch Airlines has announced it will get rid of reclining seats, which it says will give passengers more room.
The decision follows a number of surveys which found the overwhelming majority of those asked said they would like to see reclining seats on shorter haul flights either abolished or used only to set times.
Monarch said its "newly designed non-reclining ergonomic aircraft seats" will also reduce fuel emissions, and it hoped the move would promote greater harmony on their flights by ending passenger squabbles about personal space the reclining structure causes.
Director of customer experience Tim Williamson said:
"The new non-reclining design gives our customers far more 'living space' than traditional seats, without the fear of the person in front impinging on their personal space."
