Peter's Notes:
Non-stop.
No min. stay. Fare can be bought one-way for half the lowest roundtrip price. Fall travel.
Fare found on FlyFrontier.com. 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 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.
To the best of our knowledge, there is a reasonable amount of seat availability at the stated price. 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. This means we searched a range of dates to find you the best price.

I STRONGLY recommend that you only use Frontier Air as a last resort for your travel. They have recently changed the way they do business and their new business plan is to hit you for a fee at every chance. Honestly I felt as though I had gone into a bad neighborhood and was getting held-up at every corner., They charge you for EVERY bag you take on the plane, you cannot get a seat assignment before the gate unless you pay an extra $8 fee, they even charge you $2 for water on the flight. One of the most humiliating things is that just before boarding the plane they demand that every purse, bag, briefcase and carry-on must fit into one of two different measurement devices and if it does not, they charge you $100 to check the bag!!! It took an extra 45-minutes for everyone to line up and go through this humiliation. Mothers with children were trying to manage, an older woman got confused. Really, just for a few more dollars. The flight attendants HATE the new rules because it makes the passengers MAD and they blame the flight attendants. Not the attendants fault of course, but I can understand the frustration. So, be smart and use your dollars to vote for a better, less greedy approach. I say this even if you pay a few dollars more up front, because in the end you will probably NOT save anything on Frontier.
