Tight security will be in place as airlines start to bring home Britons stranded in Egypt's Sharm el-Sheikh.
The UK government cancelled flights to and from the resort on Wednesday amid anxieties a Russian passenger aircraft had been brought down by a terrorist bomb.
Only hand luggage will be allowed on the flights, with hold baggage to be transported separately afterwards.
