Fly from New York to Denver for $122 RT inlcuding taxes on Spirit Airlines.
If you can pack light and don't care where you sit, this is a great low fare available all year. We found seats available at this price for a peak summer trip over the 4th of July weekend. Please note that Spirit Airlines charges extra for carry-on luggage greater than 16x14x12 inches among many other "optional" fees. Connect in Chicago at this fare with no plane change.
An interesting point is that this fare can be found on Orbitz.com, but not on Spirit.com, where the price is $100 more. For booking info, vew our Fare Details page.
