The usual two flights on weekdays will be bolstered by an extra frequencies on December 22 and December 28.

Loganair chief commercial officer Kay Ryan said: “It’s great to see our customers travelling over the Christmas and new year period for what we know is an important time for visiting family and loved ones, and demand for the route has been high.
“We are very pleased we could help by providing these extra services for them and also for those who do still have to travel for essential work-related reasons over the holiday season.”
City of Derry airport managing director Steve Frazer added: “We are delighted that Loganair is increasing the number of flights available to and from City of Derry airport over the holiday period, allowing greater opportunity to reunite with loved ones and spread some festive cheer at this difficult time for everyone.”
