Southwest to partner with Mexican carrier Volaris

DALLAS (AP) - Southwest Airlines today announced it will sell tickets for travel to Mexico -- beginning in 2010 -- through a deal with Mexican partner Volaris.

Dallas-based Southwest earlier this year reached a similar deal with WestJet Airlines that will allow it to sell travel to Canada late next year.

Volaris was founded in 2006 and serves 23 cities in Mexico.

Both the Volaris and WestJet deals are called code-sharing, in which airlines sell tickets on each other's flights and share the revenue.

Southwest spokeswoman Beth Harbin says Volaris will do all the cross-border flying.

That's similar to the agreement in which WestJet will handle flights to and from Canada, connecting to Southwest flights at U.S. airports served by both airlines.

Harbin says Volaris plans to begin service to the U.S. next year.
