The government has been urged to set a date for the resumption of UK flights to Sharm el-Sheikh, one year after they were suspended over terrorism fears.
The flight ban to the Egyptian Red Sea resort followed the suspected bombing of a Russian airliner on 31 October 2015, killing all 224 people on board.
A group of more than 30 travel firms is calling for a decision on when direct flights from the UK can resume.
The government said British nationals' security was its "top priority".
Sharm el-Sheikh previously attracted hundreds of thousands of visitors from the UK each year, making it an important resort for airlines and holiday companies,
But flights from the UK to the airport were suspended on 4 November last year, and the Foreign Office continues to advise "against all but essential travel by air to or from Sharm el-Sheikh".
Between January and September 2015, Egypt hosted 728,942 British travellers. Numbers for the same period in 2016 dropped 70%, to 172,018 UK visitors.
More than 30 travel companies including TUI Group, Saga Holidays and Expedia have formed a partnership - The Travel Industry Egypt Advisory Group - to work with the Egyptian tourist office in London and lobby the UK government for a decision.
They fear that if the uncertainty is not ended soon, it will be too late to include the destination in their winter 2016/17 programmes.
