Indira Gandhi International Airport (DEL) is Delhi’s primary international gateway and a major South Asian hub, handling a mix of full-service carriers and budget airlines; Vistara, Air India and several Gulf and European carriers typically operate long-haul services while low-cost carriers serve domestic and regional routes. Located roughly 15–20 km southwest of Connaught Place, journey times range from 30–60 minutes by taxi depending on traffic; the Airport Express train can take about 20–25 minutes to New Delhi station with fares usually higher than local buses but competitive versus taxis. Pros: wide range of lounges, shopping and transfer options for international connections. Cons: can be busy and variable walk times between terminals, and road congestion may add delay during peak hours.
Netaji Subhas Chandra Bose International Airport (CCU) serves Kolkata as the primary international gateway and a major eastern India hub, handling a mix of full-service carriers and low-cost airlines on regional and long-haul routes. It is located about 17–18 km northeast of the city centre; taxis or app-based cabs typically take 30–60 minutes depending on traffic and can be more economical than airport-run taxis, while private car transfers and limited bus services may cost less. The airport has decent passenger facilities and international connectivity, but peak-hour congestion and occasional delays can affect comfort and transit times. For budget travellers, nearby smaller terminals serve domestic low-cost flights, offering quicker turnarounds but fewer amenities.
