The first flights from Northern Ireland to London Heathrow since Friday's disruption have arrived at the west London Airport.

Heathrow was closed for most of Friday after a fire at an electrical substation nearby that powers the airport.

The airport hopes to run a full service on Saturday, after some flights began taking off and landing late on Friday, however some flights to and from the airport on Saturday have been cancelled.

Flights from Belfast City Airport and City of Derry Airport both arrived at Heathrow shortly before 08:00 GMT on Saturday morning.

Belfast 'operating as normal'

Some disruption has remained at Heathrow on Saturday, with British Airways cancelling 80 flights in total to and from the airport.

Turkish Airlines, Brussels Airlines, Singapore Airlines, WestJet, Air India and Air Canada are also among those to have cancelled flights.

British Airways warned passengers to expect delays on those flights that were due to go ahead.

A spokeswoman from Belfast City Airport said that all flights to and from Heathrow are "operating as normal".

The airport's website shows one flight from Belfast City to Heathrow has been cancelled this evening, with a further cancellation of a flight that had been scheduled to fly from Heathrow to Belfast, but the reason for this is unknown.

Flights from City of Derry Airport are now operating as normal with no disruption, a spokeswoman said.

Dublin airport

Meanwhile, the first flight out of Dublin Airport to Heathrow on Saturday morning has also landed, delayed by about 20 minutes.

Kevin Cullinane, deputy director of communications at Dublin Airport Authority said that 30 of the 32 flights scheduled between Dublin and Heathrow are expected to operate on Saturday.

"As always, passengers seeking updates regarding specific flights should contact their airline directly," he said.

On Friday airports across the island of Ireland warned passengers that flights could continue to face disruption into the weekend, as a knock-on effect.

Six flights to and from Heathrow were cancelled at City of Derry Airport on Friday, 14 at Belfast City Airport, and 34 at Dublin Airport.

In total 70 flights between Ireland and Heathrow were affected by the fire, with further cancellations at Shannon, Cork and Knock airports.

Shannon Airport in County Clare said it had facilitated several diverted flights originally scheduled to land at Heathrow on Friday morning, including flights from Toronto, Atlanta, Bridgetown Barbados, Boston, Orlando and Newark.

Can I get a refund if my flight was cancelled?

If your flight is covered by UK law, your airline must let you choose between either getting a refund or being booked on to an alternative flight.

You can get your money back for any part of the ticket you have not used.

So if you booked a return flight and the outbound leg is cancelled, you can get the full cost of the return ticket refunded.

If you accept a refund, your airline has no further duty of care to you. If you need to make any other arrangements, you will need to do so yourself.
