Suvarnabhumi Airport (BKK) is Bangkok’s main international gateway and a full-service hub handling long-haul and regional carriers, including flag carrier Thai Airways and many major international airlines. It’s located about 30–35 km east of the city center; road transfer usually takes 30–60 minutes depending on traffic, while the Airport Rail Link connects to central Bangkok in roughly 25–35 minutes with fares typically in the low single digits (THB). As Thailand’s primary long-haul terminal, Suvarnabhumi can be more comfortable for transit connections and amenities but may feel busy and spread out, and peak-hour road transfers can be relatively costly and slow. Don Mueang International Airport (DMK) operates primarily as Bangkok’s low-cost and domestic-focused airport, serving budget carriers such as Thai AirAsia and Nok Air. It sits around 20–25 km north of central Bangkok; taxis or ride-hailing trips generally take 25–45 minutes, and public buses or the local train offer cheaper options with longer travel times. Don Mueang is often perceived as budget-friendly for fares and quick turnarounds, though facilities are more utilitarian and international connectivity is more limited compared with the larger Suvarnabhumi hub.

Delhi is served primarily by Indira Gandhi International (DEL), a major international hub handling full-service carriers and many long-haul routes, alongside a smaller domestic focus at nearby regional airports for budget operators. DEL sits about 16–20 km southwest of central New Delhi; typical travel options include the Airport Express train (around 20–25 minutes, moderately priced), taxis and app-based cabs (30–60 minutes depending on traffic, fares varying by service), and bus services (longer but cheaper). Expect a broad mix of airlines from premium network carriers to low-cost operators, with fares that can be economical on domestic sectors but higher on peak international routes. Pros: extensive international connectivity, modern terminals and lounge facilities; cons: can be crowded and traffic to the city may add significant transfer time during peak hours.

In different months, ticket prices from Bangkok to Delhi vary: minimum — $163 (June 2026), maximum — $197 (April 2027). Typically, the flight costs $179–$361.
