<p><br /> Restrictions on flights in and out of the UK have been extended until at least 7am on Sunday.<br /> </p><p><br /> The move comes as the ash cloud created by an erupting volcano in Iceland is "moving around and changing shape", according to air traffic control company Nats.<br /> </p><p><br /> If it "moves sufficiently", some domestic flights may be able to take off from Scotland and Northern Ireland.<br /> </p><p><br /> The cloud has prevented many flights from entering or leaving the UK since noon on Thursday - at a huge cost to the industry. Experts estimate the cost to British and Irish airlines could total nearly £28m per day.<br /> </p><p><br /> British Airways have cancelled all short-haul flights into and out of Britain on Sunday.<br /> </p><p><br /> A spokeswoman for the airline said the cancellation covered all flights to and from European destinations as well as domestic services.
