Arrival into MTY (Monterrey, México)
I'll be arriving on a future United flight and meeting up with someone arriving on another United flight 2 hours later.
Will I be free to remain in the secure area of the airport terminal until I choose to clear customs and immigration?
Once clearing customs and immigration, will I be allowed to re-enter (or remain in) the terminal whether arrivals or departure area? I'm not flying out till 2 days later.
