Traveling through a large and busy international airport can feel overwhelming, especially for first-time visitors. For passengers flying with Delta Airlines MEX Terminal knowing what to expect at the terminal is essential for a smooth journey. From check-in and boarding to dining, lounges, and ground transportation, understanding the Delta Airlines experience can make travel less stressful and far more enjoyable.

Mexico City International Airport – A Brief Overview

MEX Airport is divided into two main terminals: Terminal 1 and Terminal 2. Each terminal serves different groups of airlines, and they are separated by a significant distance. To help passengers move between them, the airport provides an Air train service for ticketed passengers and shuttle buses for everyone else.

Check-In

Delta passengers departing from MEX Terminal 1 can check in using one of three methods:

  1. Online Check-In – Available up to 24 hours before departure. This is the quickest way to secure a boarding pass.
  2. Self-Service Kiosks – Located inside the terminal for passengers who prefer to check in on site.
  3. Ticket Counters – Staffed counters where passengers can check luggage, make changes, or receive assistance.

Security and Immigration Process

After checking in, passengers head to the security checkpoint. Terminal 1 follows international screening standards, so travelers should be prepared with laptops, liquids, and documents ready for inspection. Once past security, international travelers are also required to clear immigration before proceeding to their gate.

Boarding Experience with Delta

Delta boards passengers in zones, starting with premium cabins, SkyMiles Medallion members, and Sky Team Elite passengers. Boarding generally begins 40 to 50 minutes before departure, though this may vary. Gate assignments are clearly displayed on monitors throughout the terminal, and staff are available to assist if a gate change occurs.

Arrivals

When arriving in Mexico City on a Delta flight, passengers disembark at Terminal 1. From there, they pass through immigration, followed by baggage claim. The baggage hall is large, but during peak travel periods it may be busy, so patience is often required. After collecting luggage, travelers proceed to customs inspection before exiting into the arrivals hall.

Lounges and Premium Services

A major advantage of flying Delta from MEX Terminal 1 is the ability to access premium lounges. Thanks to the partnership with Aero Mexico, Delta’s eligible passengers—including business-class travelers and Sky Team Elite Plus members—can relax in the Salon Premier Lounge.
