More About This Fare
Use promo code SAVE75 on FlyFrontier.com for Mon-Thu & Sat travel Apr. 24 - May 23, 2018.
This promo code expires at 11:59 p.m. ET on Apr. 23, 2018.
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's Discount Den members.
*Promo code is advertised to take 75% off nonstop domestic flights. However, this applies to the base fare only and does not apply to govt. taxes/fees nor Frontier's online booking fee (carrier interface charge), which may result in a very small actual discount on certain routes. You may be able to get a lower price by booking non-discounted fares at an airport counter and saving the $8-$38 online booking fee (carrier interface charge).
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 web check-in or at the airport.
During booking on FlyFrontier.com, you can purchase "The Works", which includes one checked bag, one standard sized carry-on bag, stretch seating, no change fees, and refundability, for much less than purchasing these items separately.

"Change policy worthless"
Flight from Denver to San Diego
Airline: United
RT/OW: oneway
Date of Flight: June 2013
Seat Class: economy
United has higher change/cancellation fees than the rest of the airlines in the same market. UA makes no attempt to match its competitors or work with the customer. The fares are the same but the change policies vary dramatically. Southwest offers a full credit on a cancelled flight or a credit in price if the new flight is cheaper to be used in one year. Frontier charges $50 but will credit back if the new fare is cheaper. United charges $150 and offers no credit if the new fare is cheaper. UA has not kept up with the market.
