These deals are all at prices below what we normally see. Some of these fares are a part of ongoing sales and some are unadvertised, which may only last a few hours. If you are interested in any of these fares, we recommend you book soon to avoid a missed bargain. All domestic fares work in the reverse direction as well.

Greenville - Orlando $34 Roundtrip for Fall Travel

Can you believe it's possible to fly for this cheap? Pack a small bag and fly nonstop from Greenville to Orlando for $34 roundtrip on Frontier. This price only includes a small personal item. If you can't travel that light, checked bag fees start at $25-$30 each way or a larger carry-on bag fee starts at $30-$35 each way. Still an excellent price if you add a bag. I found seats departing Greenville GSP on Saturday, October 13, returning from Orlando MCO on Wednesday, October 17. Other dates are available for travel on Wednesdays and Saturdays, through mid-December. Book quickly! This Frontier sale ends tonight!

Houston - Guatemala $181 Roundtrip for Fall/Winter Travel

Fly nonstop from Houston to Guatemala for $181 roundtrip on United. This amazing price is part of the "Spirit effect", which has United drastically dropping its price on this route due to new nonstop service being offered by Spirit Airlines. Travel is valid on Mondays, Wednesdays, Fridays, and Saturdays, from late October through mid-February, excluding peak holiday travel. This is a standard Economy fare on United, which includes a normal carry-on bag plus one personal item. Spirit only includes a small personal item, so go with United if the travel dates work for you.
