Chicago is served by three main airports with distinct roles. O'Hare International (ORD) is the primary international hub, typically handling the bulk of long-haul and legacy-carrier traffic—expect major carriers and many international connections. It sits about 17–20 miles northwest of downtown; travel by Blue Line train can take roughly 40–50 minutes (fares usually in the local transit range), while taxis or rideshares are commonly 30–60 minutes depending on traffic and can be more costly. Midway (MDW) is a smaller, predominantly domestic/budget-friendly airport to the southwest, about 10–12 miles from the Loop; the Orange Line rail takes around 25–35 minutes and rideshares are shorter and often cheaper than from O’Hare. Pros: O’Hare offers extensive connections and amenities; Midway can be quicker to reach and simpler to navigate. Cons: O’Hare can be busy with longer transfer times; Midway has fewer international options and can be cramped during peak periods.

Mexico City is served primarily by Mexico City International Airport (Benito Juárez — MEX), the country’s main international hub handling a wide mix of full-service and low-cost carriers, and the newer Felipe Ángeles International (AIFA), positioned as an alternative for domestic and some international budget services. MEX sits about 6–12 km (15–40 minutes) east of downtown with metro, suburban train, airport bus shuttles and taxis available; expect fares from modest metro prices up to higher taxi or ride‑hailing costs depending on time and traffic. AIFA is farther north (~40–60 km, 45–75 minutes) and usually requires shuttle, bus or car transfers, often perceived as cheaper but less central. Pros: MEX offers extensive international connections and public transit links; cons: both can be affected by heavy traffic or longer transfers, while AIFA can add extra travel time and planning for city access.

In different months, ticket prices from Chicago to Mexico City vary: minimum — $83 (January 2026), maximum — $234 (December 2025). Typically, the flight costs $137–$327.
