Giuliana's Notes:
No min. stay. Fare can be bought one-way for half the lowest roundtrip price. No peak holiday travel at this price.

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.

CheapAir charges a $9.95 booking fee.

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. This means we searched a range of dates to find you the best price.

In-flight Service
Seat Comfort
Check in line was long at 5am for a 6:15 flight; seats so close together that I couldn't recline mine, hence, no nap after waking at 2am to get to the airport. Add in two screaming young'uns, one at the back and one in front, and you have the perfect storm - not at all a pleasant experience!
