Peter's Notes:
$10 Off Promo Code Fare; Nonstop flights; Fall travel. No min. stay. Fare can be bought one-way for half the lowest roundtrip price. No peak holiday travel at this price.

Book this fare on FlyFrontier.com using promo code "5OFF" for travel through Dec. 16, 2015. Blackout dates apply: Sep. 8; Oct. 13; Nov. 24-25, 28; Dec. 1-2, 2015.

Promo code is valid for Tue/Wed/Sat travel (also, Sunday, Sep. 6) and expires at 11:59pm ET tonight, Sep. 1, 2015.

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 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.

One flight attendant-RUDE-plane delayed, so okay to use restroom. Last man in restroom did not hear the barking attendant: "You are delaying the trip for everyone, thinking of yourself." The whole plane heard her. My fried was sitting towards the front and said the man next to her planned to report her. My friend, without knowing what I was thinking, planned to say something to her as we deplaned. She stood by the door and had a fake smile. We both kept walking as we needed to catch another flight. She also yelled from the back of the plane to a gentleman closer to the front who stood up to stretch: "Sit down, you can not do that." She had dark eyes, dark hair, and was a control freak. The 2 other attendants apologized to the first gentleman who had been in the restroom and said: "We understand." I'm sure this was not the first time she behaved this way. I will think twice before flying United Airlines if I have to put up with an attendant like her. She needs to be fired or go to "Miss Manners School."
