September 8: Round Trip Airfares from Denver Fall to as Low as $30 in Frontier Airlines Fare Sale

Airfares from Denver to cities across the United States have fallen to as low as $30 round trip in a flash sale by Frontier Airlines.

On some routes, such as Denver to Fresno, California, and Denver to Fargo, North Dakota, fares have fallen by more than 80%. Others routes have seen discounts of over a third, such as flights to San Diego and Minneapolis. All reductions are calculated based on average prices recorded in Hopper’s when to buy and fly reports.

The sale began on September 8, when Frontier began manually lowering flights from its hub airport in Denver to various destinations around the country to promote the launch of its new logo and livery.

The sale encompasses flights departing during the fall months, with cut-price seats available in September, October and November. Ticket prices remained low through September 9, but analysts at Hopper said they did not expect the sale to last long.

"Promotional fare sales like this typically last only a few days," said Patrick Surry, Chief Data Scientist at Hopper, "so we’d advise researching flight prices ASAP if you’re planning to fly from Denver at some point in the next few months or if you're in the market for a weekend getaway."
