There are most likely no direct flights on the Chicago — Athens route
Chicago is served by two main airports with different roles. O’Hare International (ORD) is the city’s primary global hub, typically handling most long-haul and major carrier flights — particularly United and American — and can be perceived as mid-to-high priced for both tickets and on-site services. It sits about 17 miles northwest of downtown; travel options include the CTA Blue Line train (roughly 45–60 minutes, budget-friendly), taxis and rideshares (30–60 minutes, fare varies), and airport shuttles. Pros: extensive international connections and full services; cons: busy terminals and potential for long walks or delays. Midway (MDW) functions more as a domestic and low-cost carrier base, commonly served by Southwest and several discount airlines. Located around 10 miles southwest of downtown, it’s often quicker to reach by car or the CTA Orange Line (25–40 minutes); fares are generally modest for public transit. Pros: easier navigation and shorter transfer times; cons: fewer international routes and smaller amenities compared with O’Hare.
Athens International Airport (ATH) is Greece’s primary international gateway and a full-service hub for both legacy carriers and many seasonal and low-cost airlines, so fares can range from budget-friendly to premium depending on carrier and season. Located about 20 km east of downtown Athens (roughly 30–45 minutes by road), it is commonly reached by suburban rail or metro (around 40 minutes), express buses (about 60 minutes), taxis (30–45 minutes; metered fares), and airport shuttles. Pros include frequent flight options, modern passenger facilities and straightforward public-transport links; cons can be longer transfer times to central neighborhoods during peak traffic and higher taxi costs late at night.
