AirTran is having a sale on all nonstop routes, good for travel through May 31 if purchased by April 18. The lowest fares are offered on Tuesday and Wednesday travel, and slightly higher sale fares are available on Monday, Thursday, and Saturday travel. A few sample round-trip fares include:
The coast-to-coast fares included in the sale aren't any better than what you'd typically pay, so we suggest shopping around for those routes. But overall, there are some really swell deals to be had. Oh, and please note- these fares may also be purchased one-way.
