London is served by several distinct airports, each catering to different traveler needs. Heathrow (LHR) is the primary international hub, popular with full-service carriers and often positioned as a premium gateway; it lies about 20–25 km west of central London and is reachable by the Heathrow Express (15–20 minutes, higher fares), the Elizabeth Line or Piccadilly Line (30–60 minutes, moderate fares), and various taxis or coaches. Gatwick (LGW) to the south is a large international airport with a mix of full-service and leisure/budget airlines; trains to Victoria or London Bridge take roughly 30–45 minutes, with coach options typically cheaper but slower. Stansted (STN) and Luton (LTN) are commonly used by low-cost carriers and can be more budget-friendly overall, though they sit farther out (40–70 km north/northwest) and usually require longer transfers by train-plus-shuttle or coach (35–70 minutes, lower fares). London City (LCY) is a compact, business-oriented airport very close to Canary Wharf and the financial district (about 10 km), often popular for quick transfers and short-haul flights; it has efficient DLR connections (10–20 minutes) but fewer airline choices. Pros across the network include good rail and coach connectivity and many destination options; cons can include longer transfers to/from outlying airports, variable fares depending on carrier type, and potentially busy terminals at peak times.
O'Hare International Airport (ORD) is Chicago's primary international hub and a major connecting point for domestic and global carriers, so it typically hosts a mix of legacy and international airlines along with substantial premium and business traffic. Located about 17 miles northwest of downtown, travel to the Loop can take roughly 30–60 minutes by taxi or rideshare, or about 45 minutes by the CTA Blue Line with fares usually in the low single-digit range. Pros: extensive flight choices, many lounges and services; cons: can be busy and prone to weather-related delays. Overall, O'Hare is convenient for wide connectivity but can require extra time for transfers.
