Netaji Subhas Chandra Bose International Airport (CCU) is Kolkata’s main international gateway and typically serves both full-service carriers and a growing number of low-cost airlines on regional and long-haul routes. Located about 15–17 km east of the city center, it can take roughly 30–60 minutes to reach by taxi or app-based ride depending on traffic; airport express services aren’t frequent, while prepaid taxis and app cars usually cost in the mid-range for India. Domestic and international check-in facilities are generally modern, though peak-hour queues can form; the airport is convenient for international connections but can feel busy during holiday periods, while the distance and variable traffic mean travelers should allow ample time for transfers.

London is served by several distinct airports, each catering to different traveler needs. Heathrow is the city’s primary international hub, typically handling long-haul and premium carriers and often pricing higher on average; it lies about 24 km west of central London and is usually reached in 15–30 minutes by the Heathrow Express (around £25–£35) or 30–60 minutes via the Piccadilly Line tube (fares vary). Gatwick operates as a major secondary international airport with a mix of scheduled and low-cost airlines, roughly 45 km south of the centre and reachable by 30–40 minute Gatwick Express or 30–60 minute Thameslink/train services (moderate fares). Stansted and Luton are predominantly budget-oriented bases for low-cost carriers and charter services, each 35–65 km from central London; typical transfers are 45–75 minutes by dedicated express or coach services (generally lower-cost options), while taxis or rideshares can be considerably more expensive. London City is a compact, business-focused airport close to Canary Wharf—about 10 km east of central London—usually served by short-haul and business routes; the Docklands Light Railway gets you into the city in roughly 20–30 minutes. Pros across the network include many route choices and frequent ground links; trade-offs can be longer transfer times and varying costs depending on which airport you use and the transport mode selected.

In different months, ticket prices from Kolkata to London vary: minimum — $293 (November 2026), maximum — $306 (June 2026). Typically, the flight costs $299–$306.
