No min. stay. 20% Off Promo Code Fare; Late Summer/Fall travel. Fare can be bought one-way for half the lowest roundtrip price.
Book this fare on FlyFrontier.com using promo code SAVE20 for travel between Aug. 5 - Nov. 16, 2016. Blackout dates apply: Sep. 1-2, 5; Oct. 7 & 10, 2016. Promo code is valid for Mon-Sat travel, however, many routes are not flown on a daily basis.

This is the lowest fare found within the promo code travel period and may not be available throughout the entire travel period or on a daily basis. Some routes are seasonal and may not operate through the entire travel period. Lower fares may be available for Frontier Discount Den members.

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.

A very thoughtful FA offered to let me or my seatmate move into an unoccupied row before takeoff; the pilot was courteous and kept in touch with the passengers via PA. Flight was smooth as was the landing. I made it a point to thank him as I deplaned (he was standing at his door to greet passengers). And I told him I still think "flying" is amazing and I never get tired of it. He smiled and said that's what he likes to hear and that he would like to hear that more often. Anyway, it was a morning flight and I hope it helped him to have a good day. His expertise helped me to have a good day and allowed me to have a great visit with my daughter!
