Southwest announced back in January that it would begin flying to Mexico and a few destinations in the Caribbean, and its Android app has been updated with just a couple weeks before the July 1st launch of those new international routes. You'll be able to check in, view the status of your flight, and pull up your boarding pass (which now shows the boarding time). Otherwise, same old app, brand-new destination potentials.

The app does not yet support actually booking or managing international flights (or entering your passport info), so you'll still need to use Southwest's website for those things.
