Fuel supply problems that saw dozens of flights at Manchester Airport cancelled and left thousands of passengers stranded have been resolved.
There were 69 cancellations - 37 arrivals and 32 departures - after the issue reared its head on Sunday afternoon, with a number of other flights hit by delays.
Engineers put the problem down to a power issue, which meant its impact was felt into the early hours as some travellers were forced to pursue alternative arrangements to reach their destinations.
The airport remained open throughout the chaos, with passengers referred to their specific airline for further updates and information about their flights.
The Manchester Evening News reported that some of those left stranded had already boarded their planes when the problem arose and were made to wait for two hours on grounded aircraft.
Others managed to make progress in their bid to reach their holiday destination, but only by diverging significantly from their original travel plans.
One traveller, Matt Kirkham, tweeted: "Thanks to the chaos at @manairport we've ended up at Liverpool John Lennon at 2am on a Monday morning to fly to Faro."
In a statement, the airport said "most scheduled flights" would operate as normal on Monday after engineers resolved the issue, but warned "there will be a small number of delays and cancellations".
Passengers are still advised to check the status of their flight with their airline.
According to the consumer rights group Which, passengers whose flights are delayed for at least two hours (depending on the length of the flight) are entitled to two free phone calls, faxes or emails, free meals and refreshments appropriate to the delay, and free hotel accommodation and hotel transfers if an overnight stay is required.
Flights delayed by more than five hours mean the airline should offer the option to be rerouted on a different flight or provide a refund, just as if the flight had been cancelled.
