An airline has announced plans to repatriate British holidaymakers stranded in Sharm el-Sheikh tomorrow.
Monarch hopes to operate three "rescue flights" and two scheduled flights from the Egyptian resort to the UK.
No other airline has published details of flights for tomorrow.
The UK Government announced the dramatic decision to suspend air links with the Red Sea resort last night after a Russian air liner crashed.
Prime Minister David Cameron has said it is "more likely than not" that the plane was downed by a terrorist bomb.
Despite the announcement from Monarch, the Foreign Office would only say that "tomorrow is the hope" for bringing Britons home.
A spokesman said: "We hope it will be in place but it all depends on security.
"All the airlines are working with us to arrange similar things (to Monarch).
"It's all subject to security and there has got to be a lot of careful scrutiny of that before any plans do go ahead."
A Monarch spokesman said: "We're hoping to operate (the flights). We have not said they will 100% operate."
Speaking after talks with Mr Cameron at 10 Downing Street, Egyptian president Abdel Fatah al-Sisi said he believed there was a "good mutual understanding" and that Cairo was "completely ready to co-operate with all of our friends" on ensuring the safety of foreign tourists.
He said he hoped normality would be restored "in the soonest time possible".
Mr Sisi told reporters that British experts had looked at security in Egyptian airports 10 months ago, at the request of London, and found then that they were "good enough".
Speaking alongside Mr Sisi in Number 10, Mr Cameron said the two countries were "working intensively together in a spirit of close co-operation" and that it was "in our mutual interest to address this and get back to normal as soon as possible".
Some British tourists in Sharm have clashed with hotel staff as tensions rise over delayed flights.
Holidaymakers reacted angrily to being charged more money to stay in the resort's hotels.
Emma Smyth, who is staying about 12 miles from the airport in the Aqua Blu hotel, said the frustrations were starting to boil over.
"Because English people are frustrated and upset, they are taking it out on the staff here, which is not fair," she said.
"One English family, who are obviously upset and concerned, have asked the hotel if they can stay on. The hotel have set a charge and the tourists can not understand why they are being charged.
"They said they should be allowed to stay, and with that, one man grabbed one of the managers - they ripped his shirt, ripped his name-badge off and everything."
