Delta and Northwest announced that Northwest has begun placing its code on Delta’s daily Atlanta to Santiago, Chile, flight and its Los Angeles to Mexico City flights. Northwest customers can now purchase seats under the Northwest code on the Delta-operated service.

Last month, Northwest began offering its customers codeshare service to Sao Paul, Brazil, on Delta-operated flights from Atlanta. Northwest’s marketing alliance with Delta also provides customers service from Atlanta to Guatemala City, Guatemala, and San Salvador, El Salvador, on Delta-operated flights.

As a reminder, as part of the original codeshare agreement between Delta, Northwest and Continental, Delta Crown Room Club members entering any of the Continental Presidents Clubs and Northwest WorldClubs lounges will need to present their same-day ticket or boarding pass on the carrier whose lounge is being accessed, as well as their club membership card and government-issued identification at the front desk. The same provisions apply to Continental and Northwest lounge members entering a Delta Crown Room Club. Presidents Club and WorldClubs members will continue to have full access to each other’s club facilities.
