Ash clouds another day of air travel
Fresh eruptions at the volcano in Iceland have dampened hopes for an easing of the flight ban on Tuesday.
The National Air Traffic Services said: "Since our last statement at 2100hrs Monday, the volcano eruption in Iceland has strengthened and a new ash cloud is spreading south and east towards the UK. This demonstrates the dynamic and rapidly changing conditions in which we are working.
"Latest information from the Met Office shows that the situation is variable. The information shows that Scottish airports should be available from 0700 (local time) and more airspace over England may become available from 1300 (local time) although not as far south as the main London airports."
A Manchester Airport spokeswoman said: "Based on the overnight update from NATS, we do not expect Manchester Airport to open until 19:00 today at the earliest. Unfortunately, the latest forecasts indicate that a further deterioration in conditions is likely."
Blackpool International is operating flights to the Isle of Man and Belfast, all others are cancelled. Liverpool John Lennon Airport remains closed.
