You will have to wait a while before you can visit the Rocky Mountains via Green Bay again via Frontier Airlines. The carrier announced this week that it was cutting 43 routes across the country, including its direct flight between Green Bay and Denver. According to Colorado Public Radio, the airline cut routes to balance supply and demand better. Austin Straubel Airport Marty Piette says these things tend to happen to seasonal routes. Flights between the two cities are at the highest during the summer months, so if a pause was going to happen, just before the fall makes sense. Piette says they have talked to Frontier Airlines, and the carrier is staying in the market.

Frontier Airlines' last flight between Denver and Green Bay is August 12th.

Despite the news, Piette says passenger numbers for its other carriers, like United, American, and Delta, continue to grow. He points to the bigger airplanes flying in and out of the airport as a positive sign.
