About B3

Druk Air, operating under the IATA code B3, is Bhutan's national carrier — a small regional airline that punches well above its weight simply by flying into one of the most restricted destinations on the planet. Paro (PBH) sits in a valley so dramatic that only a handful of pilots in the world are certified to land there. That alone makes B3 worth knowing about. With 12 non-stop routes connecting 5 airports across a total network of roughly 13,070 km, this isn't a sprawling operation. It's lean, focused, and built around controlled access to a country that keeps tourism deliberately limited.

Why fly B3?

Honestly, most people aren't choosing B3 for the frequent flyer points or the lie-flat seats. They're flying it because it's often the only practical way into Bhutan. That PBH hub connects to Delhi (DEL), Kolkata (CCU), Bangkok (BKK), and a small cluster of regional cities — which means if you're routing through South or Southeast Asia, you've got real options for stitching together a trip without unnecessary backtracking. The BKK-PBH route at 1,928 km is the longest in the network, and for travelers coming from Thailand or further east, it saves a stop. Service tends to be attentive in the way small national carriers often are — staff who actually seem to like their jobs, not just reciting a script.

Tips for booking B3

Book early, especially for PBH. Seat inventory on these routes is genuinely limited and prices don't tend to drop closer to departure the way budget carriers do. If you're connecting from India, CCU and DEL both offer two routes each into the network, so shop both cities before committing. Bhutan's tourism levy is separate from your airfare — don't confuse the two when budgeting. Baggage allowances on regional routes can be tighter than you'd expect, so check your specific fare class before packing for a mountain trip. And if you're coming through BKK, build in buffer time — Suvarnabhumi connections can be unpredictable.
