Peter's Notes:
$10 off* Promo Code Fare; 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 Spirit.com using promo code 10OFF for Mon-Thu travel between Sep. 7 - Oct. 5 and Tue/Wed travel between Oct. 12 - Dec. 14, 2016. Blackout dates apply: Nov. 22-29, 2016.

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 Spirit's $9 fare club members.

Promo code takes $10 off the base fare only and does not apply to govt. taxes/fees nor Spirit's online booking fees (passenger usage fee & DOT unintended consequences fee). This promo code expires at 11:59 p.m. ET on Aug. 28, 2016. However, the lowest available fare can change at any time. Some sale fares are advertised to expire tonight, Aug. 26, 2016.

This fare only includes one small "personal item" carry-on that does not exceed 16x14x12 inches and will fit underneath your seat. Larger carry-on or checked baggage require an additional charge.

To get this fare, you must also accept a Spirit assigned seat at check-in and print your boarding pass at home or at an airport kiosk. Choosing a specific seat or using a human airport agent requires additional charges.
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.

United has higher change/cancellation fees than the rest of the airlines in the same market. UA makes no attempt to match its competitors or work with the customer. The fares are the same but the change policies vary dramatically. Southwest offers a full credit on a cancelled flight or a credit in price if the new flight is cheaper to be used in one year. Frontier charges $50 but will credit back if the new fare is cheaper. United charges $150 and offers no credit if the new fare is cheaper. UA has not kept up with the market.
