Landa Aviation is cancelling its scheduled service between Hay River and Yellowknife, within a year of launching the route.
In a letter to customers on Friday, the company said: "As of February 15, 2019, we will unfortunately be cancelling our scheduled service between Hay River and Yellowknife."
The airline also cancelled all remaining Tuesday flights from January 15, and all 9am and 4:30pm departures, asking affected passengers to call its office for information on rescheduling.
Rowe's Construction, a major local business in Hay River, said it was saddened by the impending loss of the service.
"Landa brought a great cost-effective option for us and Hay Riverites to do business in the north and abroad," wrote Ronald Schaub, Rowe's general manager.
Landa entered the market as a competitor for First Air in May 2018, looking to offer affordable return flights between the communities, six days a week.
"Thank you for your support over the past seven months," Landa's Kim and Darcy King said.
Beyond its scheduled service, Landa also operates charter services in the North.
Anyone with questions about the route cancellation and flight changes in the lead-up is invited to call Landa Aviation on (867) 874-3500.
The Kings were not immediately available for comment and the reasons for withdrawing the service are unclear.
