London is served by several distinct airports that cater to different travel needs. Heathrow (LHR) is the city’s primary international hub, typically handling long-haul and premium carriers as well as many transfer connections; it sits about 15–25 km west of central London and is commonly reached by the Heathrow Express (~15–20 min, higher fare), Heathrow Connect / Elizabeth Line (~20–30 min, mid-range fare) or Underground and buses (30–60+ min, cheaper). Gatwick (LGW) to the south is often positioned as a major international and leisure gateway with a mix of full-service and low-cost airlines; the Gatwick Express takes around 30 min to Victoria, while trains via Southern or Thameslink can take 30–50 min at lower fares. Stansted (STN) and Luton (LTN) are typically budget-leaning airports serving many low-cost carriers; both are 30–70 km from central London with coach or rail links usually taking 40–80+ minutes—coaches can be the most economical. London City (LCY) sits closest to the financial district (about 10 km), commonly used by business travelers for short-haul and regional flights; Docklands Light Railway plus short walk or taxi are often ~20–30 min and can be pricier. Pros: Heathrow and Gatwick generally offer extensive connections and onsite services; Stansted/Luton tend to be cheaper but can mean longer transfers and fewer amenities; London City is very convenient for business districts but has stricter aircraft limits and fewer long-haul options.

Istanbul is served by two main airports with distinct roles. Istanbul Airport (IST) functions as the city’s primary international hub, handling most long‑haul and flag‑carrier flights and typically offering extensive lounge and transfer facilities; it sits about 40–50 km northwest of the historic center, with driving times usually around 40–60 minutes depending on traffic, taxis and ride‑shares often costing in the mid‑range for a European capital. Sabiha Gökçen (SAW) on the Asian side is commonly used by low‑cost and regional carriers, located roughly 35–45 km from Sultanahmet; travel times can be 45–70 minutes and buses, shuttles or private transfers are common budget options. Pros: IST is well equipped for international connections and amenities, while SAW can be more economical for point‑to‑point travelers. Cons: both can be affected by heavy traffic for transfers to the city center and transfer between airports can require significant time and planning.
