Here are some crazy cheap plane flights on Frontier Airlines, starting as low as $25 one way! Book by today 8/21 and fly 8/29-10/17. You’ll only see the lower fares on midweek flights, and some are already sold out. Chicago to Orlando as low as $25! I just threw in random dates and got a $29 fare, so play with dates and see what you can get. Browse the calendar view to see everything available at once instead of trying one date at a time to see what’s already sold out.
