Here's another "buck sale" from Frontier. Base fares of $1 each way add up to $39 roundtrip after taxes and booking fees. Fares can also be bought one-way for just $20. Choose from around 30 routes at this incredibly low price. Many more routes are available for under $100 roundtrip.

If you're unfamiliar with Frontier Airlines and how this ultra-low-cost carrier differs from other airlines, read up on Everything You Need to Know Before You Fly Frontier.

Availability is limited so you must be somewhat flexible to find the lowest price. Travel days will vary by route, but generally, fares are available through mid-November or mid-December, with a 7-day advance purchase required. Avoid blackout dates between November 16-26. Pretty much all of these routes are only flown a few times each week so be sure to check out the specifics in the fare details on your route.

Tickets must be booked by 11:59 pm ET, October 3, or before seats sell out.
