Peter's Notes:
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.

Promo code takes 20% off the base fare only and does not apply to taxes/fees. This promo code expires at 11:59 p.m. ET on Jul. 29, 2016. However, the lowest available fare can change at any time.

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.
Seats are not available on all flights or all dates of travel. You may need to have flexible travel dates to find this fare. Fares for travel on holidays may be higher.
All mandatory taxes/fees are included in the price. Tax-inclusive fare may be a few dollars higher or lower depending on the airport you connect through, if any. Baggage fees, if applicable, and other optional fees are not included. Our Dealhounds found this airfare using flexible date search.

"BEWARE Carry-on fees!!"

Seat Class: economy
Check-in Experience
In-flight Service
Seat Comfort
Because we booked through Orbitz (instead of through the Frontier online site)we were charged a $25 carry-on fee for one bag. If we hadn't checked in online the night before we would not have known to quickly re-pack, and would have been stuck with $200 in fees at the counter for 4 carry-on bags. If we had waited until the gate it would have been $400. It is abvious they are charging to recoup their commissions to independent travel service companies. They also double any re-booking fee for any flight not originally booked on their website. Will never fly Frontier again.
