Afternoon Flyers,

Have been searching for an hour for info without any success... please advise.

Going to Cancun and flying Air Tran. On the return flight from Cancun, we change planes in Austin, TX with a connecting flight on Southwest to LAX. I'm assuming we go thru customs in Austin since it is the first stop in the U.S.?

Will we have to get our bags and go thru Customs or do they pick and choose the baggage of who gets searched?
Are the buildings/rooms connected and will there be a way to check the bags in directly to SW without going through security?

If all steps are needed, will a 2 hour layover be enough time to get bags, go thru Customs, check into SWA and go through security?

Thank you...
