Frontier offers the only non-stop flights from Bellingham to any city east of the Rocky Mountains.
The service will be available four times a week from May 17 through the early fall.
Kate O’Malley with Frontier says the flights will feature comfortable new planes.
O’Malley says the seasonal service to Denver last year was a big hit, so they’re excited to bring it back.
They’ll monitor how well the service performs this year before deciding if they want to bring it back again next year.
