Peter's Notes:
No min. stay. 50% Off Promo Code Fare; Travel through mid-December. Fare can be bought one-way for half the lowest roundtrip price.

Book this fare on FlyFrontier.com using promo code THANKYOU for travel between Dec. 2 - 17, 2015.

This is the lowest non-member fare found within the promo code travel period and may not be available throughout the entire travel period or on a daily basis. Lower fares may be available for Frontier Discount Den members.

Promo code takes 50% off the base fare and expires at 11:59 pm ET on Nov. 26, 2015. 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 1st 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. This means we searched a range of dates to find you the best price.

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.
