SkyTeam partners Delta and Aeromexico signaled plans to offer "joint contracting to corporate customers" as part of a newly announced "tentative agreement for a long-term, exclusive commercial alliance."

The cooperation initially would include a "coordinated" sales team, "network-wide code sharing," reciprocal benefits for elite-level loyalty program members and a $65 million investment by Delta in Aeromexico. Subject to approval from Mexican regulators, the investment would give Delta shares in Grupo Aeromexico and a seat on Aeromexico's board of directors. Delta CEO Richard Anderson described the expanded alliance as "the foundation for a joint venture."
