SUPPLEMENTARY INFORMATION:

On July 19, 2025, the Department issued a Supplemental Order to Show Cause (Order 2025-7-12) tentatively withdrawing the approval of and grant of antitrust immunity for alliance agreements concerning the JV between Delta and Aeromexico. The supplemental order provides the Department's reasoning, including detailing ongoing competitive concerns in the U.S.-Mexico air services market. If finalized, Delta and Aeromexico will cease to have a grant of ATI following a wind down period that ends at midnight on October 25, 2025. The joint venture agreement and the agreement(s) integral to the joint venture that require antitrust immunity would also be disapproved.

The Supplemental Order to Show Cause has been posted in docket DOT-OST-2015-0070 at www.regulations.gov. The order directs all interested persons to show cause why the Department should not issue an order making final the tentative findings and conclusions discussed therein. Objections or comments to the tentative findings and conclusions are due no later than 14 calendar days from July 19, 2025, the service date of the order, and answers to objections shall be due no later than seven (7) business days thereafter. In the event that no objections are filed, all further procedural steps shall be deemed waived, and the Department may enter an order making final the tentative findings and conclusions. Comments must be properly served on all interested parties in accordance with the Department's procedural regulations (14 CFR part 302).
