Boise and the Treasure Valley has seen incredible growth in population and business over the last few years.  Now, we're seeing continued growth in airlines serving the region. 

In the past 12 months, Alaska Airlines, Southwest, and Delta have added service, and now, Frontier Airlines, the low-cost carrier based in Denver has returned to service at BOI.

Tuesday marked the first non-stop flights between Boise and Denver on Frontier in around seven years.  There was an official ribbon cutting ceremony at their new departure gate at the airport.

There will be one flight from Denver to Boise and a return from Boise to Denver on Tuesdays, Thursday, and Sundays.  The inbound will arrive at BOI at 4:21 p.m., and the return is scheduled to depart at 5:45 p.m.

To celebrate the launch of the service, there have been fight deals as low as $39.  To find your best deal for dates that work for you, check out
