A very specific question this time:
Is it possible to buy and send a postcard somewhere within Benito Juárez International Airport?
If so, where in the airport can I find a post office or mailbox? Terminal 1 would be preferable in my case.

Correos de México, run by Sepomex, is the national postal service if you're sending a postcard. They have an office in the domestic arrivals area of Terminal 1. Walk to the planta baja (ground floor) and look for the pink sign in Sala/Hall A, close to Puerta 2 — they sell color postcards there too. Happy Travels!

Added from a comment posted in August 2019: Updating this for those who still send snail mail in 2019. The Correos de Mexico is now closer to Sala/Hall D and is on the top floor.
There are at least two mail / courier centers at the airport:
Aeroflash - Terminal 1, lower level (PB)
Sepomex - Terminal 1, lower level (PB
Confirming in 2024 I was able to buy postage and mail postcards from "Correos de México" in Terminal 1, just inside where cars can drop off . Closest door is Puerta 2. The location of the post offices inside the airport are accurate on google maps, it looks like there are 3 of them. They are outside the security checkpoints.
The credit card reader was down while I was there (she verified this by showing me the credit card reader and it didn't have any power), but luckily they took US dollars. $6 US to mail 6 international postcards to the United States. I had exact change.
Hardly anyone spoke English. That year of high school Spanish came in clutch!
