Departure Mierda
Entered at Reynosa (terrestrial crossing). Paid a fee since I was leaving the region (to Veracruz and CDMX). Fine.
However, upon queuing at the gate for my flight from GDL (in transit from MEX), airline reps. said I had to leave the terminal to go to a “migration booth” at departures, in order to get an “exit by air” stamp on the immigration document. Good thing I queued up early, otherwise Colimal might have erupted in a new home.
