Which is the best gateway city for flying to Bhutan?

The best gateway city depends on flight availability, visa requirements, and airfare.

Bangkok (BKK) is the most convenient gateway in terms of flight frequency, with multiple daily connections to Bhutan. No transit visa is required for most nationalities. However, airfares from Bangkok are often more than twice the cost of flying from Kathmandu.

Delhi is the next best option, offering the second-highest number of connections after Bangkok and generally shorter long-haul flights from North America and Europe. Travelers transiting through India must obtain an Indian visa, which is available as an e-visa for many nationalities.

Kathmandu, Kolkata, and Dhaka are usually the most economical gateways. Among these, Kathmandu clearly stands out: visas are available on arrival for most travelers, and there are more flights to Bhutan compared to Kolkata and Dhaka.
