Viva Aerobus, the low-cost carrier that consistently features cheap flights out of Austin to Cancun and Monterrey, is offering “free” flights on those routes for the months of July and August.

Of course, you’ll still have to pay taxes and surcharges, but you can get out the door for about $158 R/T, which isn’t bad for an international excursion.

The “free” airfares are only good for travel on Tuesdays and Saturdays, and they’re based on availability, so a bit of flexibility will help you find the best deals. Book online and enter the promotion code GRATIS to take advantage of “free” flights from Austin, TX to Mexico.

Viva Aerobus, the low-cost Mexican Airline, starts service from Austin to Cancun and Monterrey on May 1st, and to kick things off they’ve launched an airfare sale that features tickets as low as $9.99+.

That’s $9.99+ from Austin to Cancun and Monterrey. $9.99 barely buys you enough gas to get from Austin to Roundrock, so this IS a deal (and thanks to the folks at Sky Talk for tipping us off).

Tickets must be purchased five weeks in advance, and seats are limited, so plan your trip and book it NOW.
