Airlines plan to begin repatriating British holidaymakers stranded in Sharm el-Sheikh tomorrow.
EasyJet intends to operate nine flights from the Egyptian resort to the UK, while Monarch published details of five flights.
The UK Government announced its dramatic decision to suspend air links with Sharm last night after a Russian airliner crashed last weekend.
Prime Minister David Cameron has said it is "more likely than not" that the plane was downed by a terrorist bomb.
Despite the announcements from easyJet and Monarch, the Foreign Office insisted that tomorrow's flights were "all subject to security reviews".
A spokesman said: "We would hope they would go ahead as planned but there are still security issues that need to be resolved.
"We expect it to happen and hope it will happen."
A Monarch spokesman said the airline was "hoping to operate" tomorrow's flights, adding: "We have not said they will 100% operate."
The airline plans to run three "rescue flights" and two scheduled flights from the Red Sea resort tomorrow.
EasyJet has told customers it plans to operate five special flights, two scheduled flights and two that were delayed yesterday.
