("Alaska") and American Airlines, Inc. ("American") hereby jointly answer the application of Delta Air Lines, Inc. ("Delta") for an exemption
to operate scheduled foreign air transportation

in response to Alaska/American's joint request for the Department
to approve the transfer to American of Alaska's authority to serve the Los AngelesMexico City route. American plans to commence double-daily nonstop service on the Los AngelesMexico City route on June 4, 2015. On March 6, 2015, Alaska/American filed a joint reply to Delta's separately filed answer to the Alaska/ American route transfer application (Docket DOT -OST -20 15-0025). Alaska/ American hereby incorporate by reference that joint reply, in which Alaska/American stated that Delta's application
in this docket requires no substantive response because the application

is contingent and theoretical and would be rendered moot by the Department's approval of Alaska/American's routeJoint Answer of Alaska Airlines, Inc. and American Airlines, Inc. transfer application.
