A trickle of passengers have arrived at airports in Scotland after the skies above parts of the UK cleared of volcanic ash.
Scottish airspace re-opened at 7am after air traffic control company Nats lifted restrictions. But there were only a handful of domestic flights, mainly to the islands.
Glasgow Airport had been the scene of a brief flurry of flights that landed and took off on Friday and Saturday, allowing some school geography field trips to return, before the airspace was once again shut by Nats.
The airport was once again one of the few open after the volcanic eruption in Iceland pumped ash into the UK's airspace.
Only a handful of passengers were checking in for the 7am departure to Stornoway, with the departure board also listing flights to Islay, Campbeltown and Benbecula. There were no queues and international departures were listed as cancelled.
Other airports across northern England could allow flights to operate later but air traffic control company Nats said conditions were "rapidly changing" with a new ash cloud moving towards the UK.
A spokeswoman for Newcastle International Airport said the first flight was expected to arrive at 9.20am from Aberdeen. Manchester Airport said it was not planning to open before 1pm.
EasyJet said all its flights to and from northern Europe including the UK were cancelled until 5pm, but it would continue to operate routes in southern Europe.
British Airways has cancelled all its short-haul flights for Tuesday, but says it hopes to run long-haul flights scheduled to depart after 4pm, depending on a "full and permanent" opening of airspace.
