The scenario you describe falls into a grey area that is not clearly addressed by the new procedures. Consequently, it is being handled differently from airport to airport. The way we have handled this for specific flights in the past is to call the DGAC in advance at the airport you plan to enter Mexico through and explain what you want to do. This has been successful. On some occasions we have had to take up the chain of command when local officials refuse to be reasonable.

What airports do you plan to operate out of?
