Peter's Notes:
Non-stop.
Spring travel. No min. stay. Fare can be bought one-way for half the lowest roundtrip price.
After early April: Tue/Wed travel only.

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.
