Both routes will start on 24 May, with the 70-minute Teesside-Bristol service operating daily. The Derry service will initially run four times a week, moving to daily from late June.

The Teesside service will be Loganair’s seventh route from the northern airport since it returned there in February after a two-year absence. One-way fares to Bristol are from £49.99, including checked baggage. 

Derry fares are from £44.99 one-way and will be operated by a 49-seat Embraer jet already based at City of Derry airport. The new route follows confirmation the Department for Transport will continue to fund the airline’s Derry-Stansted link.

At the same time, Loganair has confirmed it will increase Derry-Glasgow flights from four a week to daily in late June.

Loganair chief executive Jonathan Hinkles said: “Loganair already serves both City of Derry and Liverpool airports, and when the opportunity arose for us to connect these two important destinations in our network following another airline’s withdrawal, we were only too pleased to step in to safeguard these connections.”
