My flight from the US was delayed and you have to switch terminals in Mexico City which takes a while with a train in between. I ran through immigration and security and made it to the gate by 2:24pm for my 2:45pm flight. The screen said Last Call still but they refused to board me.
Meanwhile, they were boarding a flight that wasn’t departing until 2:40pm and then let on Mexican nationals on a plane departing at 3:00pm only 17 mins out at Last Call without a problem.
Racist? Incompetent? You decide. Photographic evidence attached.
