Southwest says that it plans to offer flights to Mexico through a deal with discount airline Volaris starting in 2010.
The US discounter says that it has taken a step toward creating a so-called codesharing partnership with that will allow the airlines to book passengers on each other's flights.
Volaris, which travels to destinations like Cancun, Cabo, Puerto Vallarta, Acapulco, Mexico City (via Toluca), Monterrey, and Guadalajara, plans to begin flying to the US in 2009 and partner with Southwest early the next year.
For Southwest customers this is great news. The discounter has made no bones about having international ambitions, and it announced earlier this year that it would cut a codeshare deal with Canadian discounter WestJet.
As Southwest and its two intended partners basically share similar business models, customers will be able to get discount flights all though North America from anywhere Southwest flies.
And who knows what's next? Europe? Farther south into Latin America? Stay tuned.
