Cheyenne, WY – Great Lakes Airlines is offering significant discounts on airfares. The reduced prices are good for flights booked before next Friday. The Cheyenne-based regional carrier serves six Wyoming communities with flights to Denver. Great Lakes Director of Sales and Marketing Monica Taylor says this is the first time they have ever tried a system-wide fare sale. If it's successful, she says they'd like to offer three or four of these a year. Under this deal, the cost of a round-trip flight from Cheyenne to Denver goes from $238 to $78. A trip from Laramie to Denver and back would only be $98. Ordinarily, it's $242.
