Travel plans for thousands of air passengers have been thrown into chaos by an aviation fuel supply problem at Manchester airport.
The airport said some airlines may not be able to refuel there, and that some might decide to cancel, divert or delay some flights from 6pm on Wednesday into Thursday morning.
The airport advised passengers travelling Wednesday night and Thursday morning to check with their airlines before going to the airport.
The airport's fuel supply comes from the Essar refinery near Ellesmere Port on Merseyside.
The airport uses around three million litres of aviation fuel per day. This is the equivalent of 79 road tankers which carry approximately 38,000 litres per vehicle.
The fuel supply comes from the refinery via a pipeline which is capable of pumping 250,000 litres an hour.
The fuel storage centre at Manchester airport is operated by MASHCo - a joint venture between Exxon Mobil, Shell, BP and Q8.
The oil companies are contracted directly directly by airlines to supply aircraft fuel via MASHCo.
Virgin Atlantic has two flights leaving from Manchester at about midday on Thursday - one to Las Vegas in Nevada, the other to Orlando, Florida.
A spokeswoman for the airline said: "We are not unduly concerned at the moment and are waiting to hear more news from Manchester. Our planes could have a 'pit stop' in Ireland to refuel there if necessary."
