if it was here for a meeting/summit or in an official diplomatic visit the aircraft would have gone right after landing directly to the president's hangar.
Are you even aware that the 110th IPU Assembly (formerly known as the Inter-Parliamentary Conference) is being held in Mexico City?
This already started April 18th and ends on the 23rd. 6 Kuwaiti MP
's are attending this meeting in Mexico City and thus their use of an official Kuwaiti State aircraft.
Now, I dont know why the aircraft was not parked at the president's hangar but the below URL's will act as back-up to my original answer that it (A310) is being used for official state and/or diplomatic visits, rather than for 'leisure' purposes; regardless of where MEX
authorities decided to park the aircraft.
