Eastern Airways has launched a new route to Esbjerg, doubled the number of Newquay flights and restarted its Jersey services from its Humberside base.
The new Denmark three-weekly service will commence on 14 December and will operate on Mondays, Wednesdays and Fridays year-round.
Additionally, the line’s Newquay service has doubled in frequency to a four-times weekly route for the summer, with services operating on Mondays, Thursdays, Fridays and Sundays from spring.
Meanwhile, Jersey sees an extended season and is back weekly from Saturday 13 May.
Roger Hage, commercial director, Eastern Airways, said: "This is a major dual development for the Humber region as we join the UK centre for renewable energy with Esbjerg in the west of Denmark.
"The renewable energy sector is fundamental to the employment and growth in the Humber as the energy estuary."
