Book this fare on FlyFrontier.com using promo code SAVE30 for Tue/Wed/Sat travel between Aug. 3 - Nov 16, 2016. Blackout dates apply: Oct. 8, 11, & 12, 2016.

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.

Seat Comfort
We fly Frontier quite often and do so because the service is usually good at every turn. The return flight on the trip was an exception as the all-male cabin crew were just plain cranky. They weren't rude, but they also weren't as friendly as we're used to experiencing with Frontier. I suppose that everyone is entitled to a bad day, but all three? Maybe they should throw a female into the mix to keep spirits up.
