Cornwall flights from Newquay Airport back to normal
Flight schedules at Newquay Airport have returned to normal after disruptions caused by ash from an Icelandic volcanic eruption.
The UK's Met Office has said however, ash from the Grimsvotn volcano might return to affect much of the country on Friday.
Airport bosses hope any return will not cause further delays to passengers go on half-term holiday breaks.
Travellers have been told to check their airline's website for updates.
Forecasters said that if eruptions continued at "current variables", all areas with the exception of East Anglia and south-west England might be affected by ash, with the potential to disrupt flights.
"On Friday, at between 35,000 and 55,000ft, there could be a risk of a high concentration of ash covering most of the UK," a spokesman said.
