Carry-On Only for Mexico City: Airlines, CDMX, and Packing Tips

Mexico City is a vast, culturally extraordinary destination that rewards careful packing. The key variables are which airport you fly into, which carrier you use (free carry-on versus paid add-on), and two quirks that surprise almost every first-time visitor: the altitude UV intensity and the cold evenings despite a tropical location. Get those right and your carry-on will serve you well across Condesa, Roma, Polanco, and the historic center.

Airlines: Aeromexico vs Budget Carriers

Aeromexico permits one main bag up to 55×40×25 cm plus one underseat personal item when included or purchased. Their combined limit is 10 kg for Basic families, or 10/15 kg for Classic/Flex families by region; the United States row is 10 kg for all. Light, distinct from Básica, excludes the main bag where offered. Check the table row for the complete itinerary.

Volaris includes a 45×35×20 cm personal item on every fare. Zero and Basic exclude the main cabin bag; Plus includes one, and Zero/Basic can purchase it. The main bag is 55×40×25 cm and at most 10 kg; both pieces together must not exceed 20 kg. Check My Trips for the actual fee and entitlement rather than assuming a fixed gate price.

AIFA (Felipe Ángeles Airport): Factor in the Distance

AIFA — officially Felipe Ángeles International Airport, code NLU — opened in 2022 to relieve congestion at MEX. It handles budget carriers and some domestic routes. The airport is located approximately 50 km north of central Mexico City, near Santa Lucía in the State of Mexico. Door-to-door transfer times to the city center run 90 minutes to two hours or more in heavy traffic.

Before booking a flight into AIFA based on a cheaper fare, calculate the true cost: additional rideshare or taxi fees, extra time, and potential fatigue on arrival. For most visitors, the convenience of MEX outweighs a modest price difference. Check which airport your flight uses before confirming the booking.

Packing for Mexico City (CDMX)

High-SPF sunscreen under 100 ml. Mexico City's altitude of 2,240 meters means UV radiation intensity is considerably higher than at coastal or sea-level destinations. The thinner atmosphere filters less UV. Pack a high-SPF sunscreen in a travel-size container of 100 ml or less. Apply it daily, even when skies are overcast. This is one of the most commonly overlooked packing needs for CDMX visitors.

Light jacket for evenings. Despite Mexico City's position within the tropics, temperatures follow an altitude pattern rather than a tropical one. Daytime highs of 22–25°C in spring can drop to 12–14°C after sunset. Evenings in Condesa or Roma Norte often call for a layer. A lightweight fleece or a smart-casual jacket that works for both restaurant evenings and cool afternoon walks takes minimal bag space and prevents genuine discomfort.

Rain layer for June through September. Mexico City's rainy season runs approximately June through September, with reliable afternoon and evening storms. A compact packable rain jacket weighing under 300 g handles these storms comfortably. The rain comes hard and fast and then stops — a poncho or rain jacket lets you continue your day rather than sheltering for an extended period.

Comfortable walking shoes. CDMX is an enormous city but many of its best areas — Roma, Condesa, Coyoacán, the historic center — reward walking. Cobblestones and uneven pavements are common. Pack well-cushioned shoes with rubber soles. The metro is also an excellent way to cover large distances; comfortable shoes handle both the walking and the stations easily.

Stomach medicines in carry-on. Traveler's diarrhea is a realistic risk in Mexico City, particularly in the first few days as your gut adapts. Pack oral rehydration salts, loperamide, and antacids in an accessible part of your carry-on so they are available immediately on arrival. Mexican farmacias are well-stocked alternatives, but having medicine on hand prevents a difficult first night.

Benito Juárez Airport (MEX)

MEX is one of Latin America's busiest airports and sits unusually close to the city center — Terminal 1 and Terminal 2 are connected by a free inter-terminal shuttle. Security wait times can be long during peak periods. Arrive 2.5 hours before international departures and 90 minutes before domestic flights. The airport metro station (Terminal Aérea) connects directly to the city center at low cost, making it an easy and cheap option for arriving travelers comfortable with the Mexico City metro system.
