Jocelyn's Notes:
Fall/Winter travel. No min. stay. Fare can be bought one-way for half the lowest roundtrip price. No peak holiday travel at this price.
This fare requires an overnight layover in Denver. Travel between September and February. Blackout dates apply: Nov. 18-28 & Dec. 16, 2016 - Jan. 3, 2017.

Fare found on FlyFrontier.com. Frontier charges a $30-$35 fee each way for carry-on bags larger than 18x14x8 inches and a $25-$30 fee each way for first checked bag no larger than 62 linear inches (length + width + depth) and no heavier than 50 pounds. These bag fees apply to online purchases before check-in. Higher fees apply at the airport.

During booking on FlyFrontier.com, you can purchase "The Works", which includes one checked bag, one carry-on bag, stretch seating, no change fees, and refundability, for much less than purchasing these items separately.
