Low-cost carrier Frontier Airlines will launch non-stop service between its Denver hub and Minot, North Dakota from 5 November.
It will operate four times weekly on the route with its Embraer 190 aircraft.
"As we've continued to enjoy such a fantastic response to our Bismarck and Fargo service, it's clear there is a considerable need for Frontier's high-value, low-fare service throughout North Dakota," says Daniel Shurz, Frontier's senior vice president, commercial.
Frontier also announced that it would bring forward the relaunch of its Denver to Fargo service to 9 November today, a week earlier than previously planned.
The airline will compete with United Airlines between Denver and Minot, which operates non-stop flights between the two cities.
