| There are hardly words to describe how abysmal this airport is. I had 2 hours to make a connection from Mexico City to Hartford. American Airlines should have known better than to book such a short layover through this wretched place. The plane was delayed 15 minutes on the tarmac and then 10 more at the gate when no agent was available to operate the entryway. Then, there was an interminable walk through unmarked hallways to an interminable immigration line. There, after being herded to the automated kiosks, I was herded to wait over 40 minutes for an agent who was gleefully asking smug questions of every U.S. citizens in line, spending an average of 5 minutes with each person. Other lines moved more quickly at this point, so this is clearly a particular agent’s power trip. At this point, when I tried to find where to re-check my luggage, an agent rudely asked me for when my connnection was. This was the first time I was asked about my connection time, notwithstanding the “short layover” stickers that had been plastered all over my suitcase. At this point, the rude American Airlines employee told me to go to a different line from the one which I was standing, with now explanation. I assumed, incorrectly, that this was an expedited line, since I still had around 40 minutes to catch my flight. It was not. The door that the rude agent sent me through took me outside of security to the airline agents for rebooking. I learned from another agent that I had been sent there because other agents decided that the remaining 40 minutes was not sufficient for me to make my connection. And, throughout the process, the half-dozen or so staff members that I had the misfortune of interacting with were extraordinarily rude and impassive to the fact that they were part of an inefficient and abusive machine that was making thousands of passengers miserable. Unfortunately, I need to make this same trip for work several times a year. In the future, it will cost me around a hundred dollars to book itineraries on a different airline (probably Delta) in order to avoid this airport. It will be worth every penny.
