MEXICO CITY (Reuters) -Carriers Delta and Aeromexico on Tuesday argued against winding down their antitrust agreement, as proposed by the U.S. Department of Transportation, while asking for an extension to do so if needed.

The two, in a filing to authorities, requested the deadline be extended to March 28 of next year, the end of the sector's "winter season," from the current October 25.
