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 between Sep. 16 - Dec. 16, 2015. Blackout dates apply: Oct. 13; Nov. 24-25, 28; Dec. 1-2, 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.

"Not fun anymore."

Seat Comfort
Remember when traveling was fun? It had a certain air of romance & adventure? I miss that. Now it's just a hassle, a way to get from Point A to Point B. No tearful goodbyes or joyous welcomes. No in-flight food. No graciousness. I guess now if I want a decent size seat, flight attendants without an attitude, or not having to pack the bare minimum so I have to lug my bag around and squish it in the overhead bin. I'll have to pay extra. The only good thing is online check in. It's just not fun anymore.
