Chicago is served by two primary airports with different roles. O’Hare International (ORD) is the city’s major international and connecting hub, typically handling a wide mix of legacy carriers and many long-haul flights; it’s often perceived as mid- to higher-priced for premium services but can offer competitive fares on major routes. Midway (MDW) is a smaller, more budget- and domestic-oriented airport that usually hosts low-cost and leisure carriers and can be cheaper for short-haul trips. O’Hare lies about 17–20 miles northwest of downtown (roughly 30–60 minutes by road depending on traffic) and is linked by the CTA Blue Line (around 45–55 minutes, modest fare). Midway sits roughly 10 miles southwest (about 20–35 minutes by car) and connects to the city via the CTA Orange Line (around 25–35 minutes, low fare). Pros: O’Hare offers extensive international connections and many amenities; Midway can be quicker for domestic travelers and easier to navigate. Cons: O’Hare can be busy and spread out; Midway has fewer long-haul options and can feel more crowded during peak leisure periods.

Heydar Aliyev International Airport (GYD) serves as Azerbaijan’s main international gateway and a regional hub for full-service carrier Azerbaijan Airlines alongside several international carriers; it can also handle budget operators on select routes. Located roughly 20–25 km southeast of Baku city center, typical transfer options include taxi rides of about 20–40 minutes (fares vary by service and traffic), airport shuttle buses taking around 40–60 minutes for modest fares, and private transfers. The terminal is generally modern and well-equipped, offering lounges and duty-free shopping, which can make connections comfortable. Downsides can be longer waits at peak times and additional local transport time compared with nearer urban airports.
