Airspace in Scotland, Northern Ireland and parts of northern England is due to reopen on Tuesday after days of travel chaos caused by a volcanic ash cloud.
The air traffic control body, Nats, said from 0700 BST on Tuesday airspace as far south as a line between Teesside and Blackpool would reopen.
It added that mainland Scottish airports would be open.
Nats said restrictions to airspace above the rest of England and Wales could be lifted later on Tuesday. Gavin Hewitt reports.
