Jet2 (United Kingdom) (LS, Leeds/Bradford) has suspended operations at Belfast International owing to what it called "increased safety concerns due to the airport's ongoing runway resurfacing programme." For its part, airport authorities said they had received notification that "one Jet2 aircraft has been exhibited engine-related problems on three occasions," but that "no other airline, nor aircraft of the unspecified type, had reported any issues." While some flights have temporarily operated from Belfast City and Londonderry City of Derry on April 8 and 9, Jet2 will resume operations from Belfast International on April 10 and exclusively operate on the airport's North-South runway not affected by the resurfacing work.
