Finally!!! Got my return flight on Southwest. Was able to secure both flights at the $79 internet fare each way and am hoping Ding will do better, but am just happy I got the flights.
I booked the $79 MHT to MCO fare as soon as I confirmed my dates. Then I waited...sure enough there was a Ding fare for $49. Cancel the old and rebook the new. $115 RT...how can you beat that? You could not drive for that price.
