Jet2.com is to resume flights from Belfast international airport today after temporarily suspending operations due to safety concerns.
The budget carrier stopped flying from the airport on Monday due to its runway maintenance programme.
Jet2.com switched flights to George Best Belfast city airport and City of Derry airport.
It was the only airline to do so and the Civil Aviation Authority said it was confident the airport was safe.
Jet2.com said it would now use the Belfast international’s alternative runway.
In a statement on its website, the airline said: “Following our decision to temporarily suspend operations at Belfast international airport, due to safety concerns during the current maintenance programme on the main runway, we have today (Tuesday) come to an agreement with the airport that we will now operate all our flights using the alternative North/South runway.
“This will take effect from Wednesday 10th April, until further notice.”
It added: “This decision follows close consultation with the airport and a detailed safety assessment conducted today.
“All our customers due to travel from Belfast international this week should go to the airport as normal.
“We would like to apologise for the inconvenience this has caused however the safety of our customers is of paramount importance and we will not operate from Belfast international airport’s main runway until the resurfacing has finished.”
The airport said on Monday that one Jet2.com aircraft had reported engine-related problems on three occasions, but there was no conclusive evidence connecting this with the runway.
Work to re-surface the runway has been disrupted because of recent weather, the BBC reported.
