I know there are quite a few Mexican spotters on here and want to pose a question to them. On Friday I am taking the new Mexicana flight 861 from JFK-MEX. The flight makes a brief, 45 minute, stop in Cancun. I have heard conflicting accounts of how immigration/customs works with these flights. Since the ground time is a mere 45 mintues, do passengers continuing on to MEX stay on the plane in CUN while the CUN-MEX pax board? Or, do we all have to get off the plane and go through immigration/customs in CUN?
Obviously, MX does this flight every day, and there are plenty of people who take the flight JFK-MEX, but I'd just like to know the procedure, if anyone knows.
