Peter's Notes:
20% off* Promo Code Fare; Late Summer/Fall travel. No min. stay. Fare can be bought one-way for half the lowest roundtrip price.
Book this fare on FlyFrontier.com using promo code SAVE20 for Sun-Thu & Sat travel between Aug. 30 - Nov. 16, 2016. This fare may require a long layover in Denver.

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 Aug. 29, 2016.

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.

Flexible travel dates may be required to find this rate; seats may not be available on all flights or all dates of travel. Holiday periods may be excluded. We monitor the availability of the fare and take efforts to remove and/or modify fares when no longer available.
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.

We arrived at 8:15 am.for our 10:15 flight We were late in leaving DC as the plane was late in arriving, then TSA decided that they needed to check everyone boarding pass and ID before we are allowed to board, I guess they thought we changed once we cleared security. When arriving in Chicago, we had to run from A45 to B18 because they ere already boarding.So NO LUNCH and NO time to get any!Peanuts do not help much. Then had to stop in St. Louis that we were nort aware of and finally got to Phoenix at 3pm with the time changes we were now 12 house with only peanuts!For for sale would have been good. Also when animals are permitted to travel, they must be in a container that allows then to stand up and completely turn around.Why is this NOT the same for HUMAN passengers????????
