who we are

DENVER (May 22, 2005) - Frontier Airlines (Nasdaq: FRNT) today will begin new service between its Denver International Airport (DEN) hub and Tulsa International Airport (TUL). The two daily non-stops between Denver and Tulsa will be aboard 70-seat Canadair Regional Jets, operated by Horizon Air as Frontier JetExpress and will offer dozens of connecting opportunities to Frontier cities throughout the West.

"We would like to thank the Tulsa Airport Authority for their support and hard work as we ramped up our new service in anticipation of today’s first flights between Denver and Tulsa,” said Andrew Hudson, senior director of marketing and communications. “The new service comes just in time for the start of the busy summer season so that Tulsa travelers can take advantage of the great weather and outdoor activities like biking, hiking and rafting, offered in the Rocky Mountains."

Mary Smith, director of marketing at the Tulsa Airport Authority said, "Tulsa travelers are thrilled to welcome Frontier Airlines, a low fare and reliable choice for travel to the West. The schedule allows for a day's work in Denver without an overnight stay, all at fares that will bring a welcome relief to our community."

Following is the Tulsa flight schedule (all times given in local arrival or departure city times):
