Fuel supplies at Manchester Airport have returned to normal, airport bosses confirmed on Thursday.
Production problems at its supplier meant the airport temporarily did not have enough aviation fuel over Wednesday.
Fears were voiced that it could prompt a string of flight cancellations and delays if stocks were not replenished until early on Thursday morning.
Thirteen flights were delayed because of the glitch, with 12 waiting for less than 30 minutes, while 17 departure flights also made a short stop at other UK airports to top up fuel before completing the onward journey.
A total of three million litres of fuel was supplied overnight to the airport's fuel storage facility and meant operations returned to normal at 8.30am today, the airport said.
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.
Chris Formby, operations director at Manchester Airport, said: "Although we initially warned about the potential for some cancellations and diversions based on the information from the fuel companies yesterday afternoon, disruption to passengers has been kept to an absolute minimum thanks to the airlines and the Essar refinery.
"On behalf of the thousands of passengers travelling today and last night, we would like to thank our airline partners for the huge effort they put into contingency planning to mitigate the highly unusual problem with the fuel supply."
