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.

Considering the hassle of flying today this was not a bad flight. The departure delay was probably handled as efficiently as could be. The boarding was pretty efficient on both ends. Economy clas is economy class no matter what. All in all I would say it was an "average" flight.
