Frontier Airlines, a popular ultra-low-cost carrier in the United States, has steadily expanded its international reach, including service to and from Mexico City International Airport , commonly referred to by its IATA code MEX. Frontier Airlines MEX Terminal operates out of Terminal 1, one of the busiest and largest terminals in Mexico. Whether you’re arriving in or departing from Mexico City on a Frontier flight, understanding Terminal 1’s layout, services, and procedures will help ensure a smoother travel experience.

Overview of Terminal 1

Terminal 1 is the older and larger of the two terminals, handling both domestic and international flights. It serves a wide range of airlines, including major international carriers and low-cost airlines like Frontier. Terminal 1 is known for its length and size, stretching over 3 kilometers, which can make navigating it a bit of a challenge for first-time visitors.

Arriving at Terminal 1 for Departure

Passengers departing on a Frontier Airlines flight from MEX should plan to arrive at least 3 hours before an international flight. Since Frontier is a budget airline, many services such as seat selection, checked baggage, and in-flight refreshments come at an additional cost, so it's important to manage these services online in advance, if possible.

Frontier Airlines passengers can check in either:

• Online via the Frontier website or mobile app, starting 24 hours before departure, or

• In person at the check-in counters located in Terminal 1.

If you’ve already checked in online and have a mobile or printed boarding pass, you can head directly to the baggage drop counter, if you have checked luggage. Otherwise, travelers without checked baggage may proceed directly to security.

Security Screening

After checking in, passengers must go through security screening before reaching the departure gates. The security process at Terminal 1 is generally efficient but can experience delays during peak hours. Be prepared to remove electronics and liquids from your carry-on, and have your boarding pass and identification readily accessible.

Post-Security Amenities and Services

Once through security, Terminal 1 opens up into a wide area with many services and amenities, including:

• Restaurants and Cafés: From quick-service eateries to sit-down restaurants, Terminal 1 offers various food choices. While Frontier doesn’t offer complimentary meals on board, travelers can grab food before boarding.

• Duty-Free Shopping: International travelers can explore a selection of duty-free shops selling perfumes, alcohol, snacks, and souvenirs.

• Currency Exchange and ATMs: Several exchange kiosks and ATMs are available.

Boarding Frontier Flights

Frontier typically begins boarding 30–45 minutes before departure. Make sure you are at the gate early, as Frontier is strict about boarding times. Since seat assignments, baggage allowances, and other services depend on what you’ve purchased, make sure everything is confirmed in advance.
