The merger of Southwest and Airtran has gone on for quite some time and the transition of Southwest flights to international destinations that Airtran previously flew has been a slow process. In July 1, they started international flight from select cities. I was trying to find out when and where they would start expanding their cities but couldn’t find the information. It looks like they have now released this information in the form of maps which can be found here. Instead of going through the maps yourselves, I’ve posted them below in date order:
I did a dummy booking from Austin to Cancun after Nov 2 to see if it would let me book. I noticed this message at the top of the page.
So it looks like they haven’t officially been given the “go” to operate these flights but hopefully they won’t be pushed back past the original scheduled date. That being said, you never know what might happen so make sure you can be flexible with your plans if you need to change the dates if necessary.
I am excited that all of these routes will be starting before the end of 2014 because I have a Companion Pass that I want to maximize for these international destinations.
