UK low-cost operator Jet2 has stopped flying to Belfast International Airport, citing safety concerns with a runway maintenance programme.
Jet2 is switching to Belfast City for its domestic flights to Leeds Bradford. The change takes effect on 8 April. It has yet to disclose plans for its international services.
"We will not operate from Belfast International Airport until we have reassurances on the runway maintenance," says the carrier.
The airport is undergoing runway resurfacing work but its operator says work has been held up for the past three weeks by poor weather.
During this time, it says, one of Jet2's aircraft apparently exhibited "engine-related problems" on three occasions.
Jet2 says a Boeing 737 was involved in the incidents.
"No other airline, nor indeed any other Jet2 aircraft or aircraft of this type, has reported any similar issue," says the airport operator.
"A full investigation is underway to assess what actually occurred," it adds, stating that safety is "non-negotiable".
But is also points out: "At this stage there is no conclusive evidence connecting these reported problems with the runway maintenance at Belfast International Airport."
