Why Bangkok is the easiest connection in the world
Bangkok to Paro is direct on Drukair (KB153 most days; ~4 hours; morning departure). No long-haul fatigue, no hub overnight, no jet lag worth speaking of. For Bangkok-based couples — Thai premium travellers, expatriates, business travellers extending — this is the trip where the journey actually starts feeling like a holiday on Day 1 rather than Day 3. Most other source markets need a hub overnight; Bangkok travellers don't. The Drukair morning flight is a pleasant 4-hour leg with the Himalayan range visible on the descent.
