Use miles for the long-haul leg only to Bhutan

Quick summary

Neither Drukair nor Bhutan Airlines belongs to Star Alliance, Oneworld, or SkyTeam — which means no alliance miles can be redeemed for the final leg into Paro (PBH), the only international airport in Bhutan. The practical workaround: burn business class miles to Bangkok or Singapore, then buy a separate cash ticket on Drukair or Bhutan Airlines for the short hop into Paro. Air Traveler Club’s analysis of 3 major hub routings shows this split approach consistently delivers better value than any all-cash itinerary from Europe, the US, or Australia.

The key caveat is that separate tickets carry real misconnection risk, and Paro’s mountain approach means weather delays are common. This article covers which miles programs reach the best hubs, how to structure the split booking, and where the strategy breaks down.

Bhutan has exactly one international airport: Paro (PBH), served exclusively by Drukair and Bhutan Airlines. Neither carrier holds membership in any global alliance. That single structural fact shapes every award-booking decision for travelers heading to the Kingdom — and it means searching for “London to Paro” on any alliance award engine is a guaranteed dead end.

For UK, European, US, and Australian travelers planning a Bhutan trip in 2025 or 2026, the correct approach is a two-ticket strategy: redeem miles for the long-haul leg to an Asian hub, then purchase a separate cash ticket for the Paro sector. Air Traveler Club’s routing analysis across London, New York, and Sydney departures identifies Bangkok (BKK) and Singapore (SIN) as the two most efficient hub choices, with Delhi (DEL) and Kolkata (CCU) as viable alternatives for travelers already positioned in South Asia.

The math is straightforward. Business class cash fares from London to Bangkok run roughly £2,800–£3,800 return. A separate Drukair or Bhutan Airlines cash ticket from Bangkok to Paro typically costs £300–£500 return. Redeeming Avios or KrisFlyer miles for the London–Bangkok leg — and paying cash only for the short Bhutan sector — can reduce the total outlay by £1,500–£2,500 per person compared to booking everything in cash.

Which miles to burn and which hub to target

The two strongest programs for reaching Bhutan’s gateway hubs are Qatar Airways Avios and Singapore Airlines KrisFlyer. Qatar operates London Heathrow to Bangkok via Doha daily, and the route is fully bookable with Avios in business class — the same cabin where cash prices are highest and miles deliver the most leverage. KrisFlyer covers London to Singapore directly on Singapore Airlines metal, and Singapore is itself a Drukair gateway with direct PBH service.

For Star Alliance travelers, Thai Airways’ Royal Orchid Plus program allows redemptions on TG-operated Bangkok flights, making it a workable path to BKK for those with United MileagePlus, Air Canada Aeroplan, or other Star miles that transfer or credit to ROP. Cathay Pacific adds a third Oneworld option: London to Bangkok via Hong Kong, bookable with Asia Miles, which suits travelers who hold Cathay status or have Asia Miles balances to deploy.

The principle across all of these is identical: use miles where cash prices are highest (the 10–13 hour long-haul), and pay cash where miles have no leverage (the 2–3 hour Bhutan sector). Drukair and Bhutan Airlines use fixed seasonal pricing on their routes, so there is no dynamic fare advantage to chasing on the PBH leg anyway. You can check current flight options to Bhutan from Europe to benchmark cash prices before deciding which hub to target.

The routing map: origin to hub to Paro

Both Drukair and Bhutan Airlines publish scheduled services from Paro to Bangkok, Delhi, Kolkata, and Kathmandu. Bangkok is the most popular gateway for Western travelers because it offers the most frequent connections, the widest range of alliance carriers flying in, and a comfortable overnight option if you want a buffer between your long-haul arrival and your Paro departure. The Tourism Council of Bhutan confirms Paro as the sole international entry point, so every routing decision flows through one of these four cities.

The table below maps common origin regions to their most practical hub and miles combination. Treat the routing as a starting framework — actual award availability varies by program, season, and how far in advance you search.

Why Bangkok works better than Delhi for most Western travelers

Delhi is geographically closer to Paro and has more frequent Drukair services, but it introduces a complication: Indian visa requirements for most Western passport holders. Bangkok requires no advance visa for UK, EU, US, or Australian citizens for stays under 30 days, making it a frictionless overnight stop. That matters when you are already managing two separate tickets and a mountain airport with weather-dependent operations.

Bangkok also offers more alliance carrier options flying in. Qatar, Thai, Cathay, Singapore Airlines, and a dozen other carriers serve BKK — meaning award availability is broader and you have more flexibility if your first-choice program has no space. Singapore is the better choice specifically for KrisFlyer holders, since Singapore Airlines operates its own London–Singapore route and Drukair runs a direct SIN–PBH service, creating a clean two-ticket itinerary without a third city.

For Australian travelers, the Australia–Bhutan split ticketing analysis shows A$800–1,200 in savings using the same Bangkok hub approach, with Qantas or Jetstar covering the Australia–Thailand leg and Drukair handling the Paro sector. The principle is identical regardless of origin: decouple the long-haul from the Bhutan leg, and use miles where they deliver the most value.

Kathmandu is worth mentioning for travelers who want to combine Bhutan with Nepal. Both Drukair and Bhutan Airlines serve KTM, and Kathmandu is reachable on a range of alliance carriers. It is a niche routing but a logical one for a combined Himalayan itinerary.

When the two-ticket strategy breaks down

Paro International Airport has one of the most technically demanding approaches in commercial aviation. The runway sits at 2,235 metres above sea level, surrounded by peaks exceeding 5,000 metres, and only a small number of pilots are certified to fly the approach. Weather cancellations and delays at PBH are genuinely common, particularly during monsoon season (June–September) and in winter fog periods.

When you hold two separate tickets, a delay or cancellation on the Paro leg does not trigger any airline obligation on your long-haul booking. You are on your own. This is the central risk of the split-ticket approach, and it is not theoretical — travelers have missed long-haul connections because Drukair cancelled a morning PBH departure with no same-day alternative.

Three scenarios where the strategy becomes problematic:

• Tight connections at the hub: If your long-haul arrives in Bangkok at 06:00 and the Drukair departure to Paro is at 09:00, you have almost no margin. Immigration, baggage reclaim, and check-in for a separate ticket at a different terminal can take 90 minutes or more. Always plan an overnight at the hub.
• Monsoon season travel: June through September sees the highest rate of PBH disruptions. If Bhutan is on your itinerary during this window, build at least one extra buffer day at your hub city before any time-sensitive onward commitment.
• OTA through-fares: Some online travel agencies display itineraries that appear to connect your origin city all the way to Paro on a single booking. These are revenue tickets — you still cannot use alliance miles for the PBH sector, and the through-fare pricing rarely beats the split-ticket approach for business class travelers.

Travel insurance that covers missed connections on separately ticketed flights is essential here. Standard policies often exclude this scenario; look specifically for a policy that covers self-transfer or independent connection risk.

How to book this routing before your preferred award space disappears

Business class award space on Qatar LHR–BKK and Singapore Airlines LHR–SIN typically opens 355 days in advance, but the most desirable dates — particularly around Bhutan’s peak festival season in spring (March–May) and autumn (September–November) — fill quickly.

• Search the long-haul first: Lock in your miles redemption for the hub leg before touching the Drukair booking. Award space is the scarce variable; Drukair cash tickets are available closer to departure.
• Target Bangkok over Delhi: Use Google Flights or the Qatar Airways award search to check LHR–BKK availability in business class, then cross-reference with KrisFlyer for LHR–SIN if you hold both currencies.
• Book the Paro leg directly: Purchase your Drukair or Bhutan Airlines ticket at drukair.com.bt or bhutanairlines.bt after confirming your hub arrival. Choose a morning PBH departure to maximize recovery time if your long-haul is delayed.
• Build in an overnight at the hub: One night in Bangkok or Singapore is not a cost — it is insurance against the misconnection risk that comes with separate tickets into a weather-sensitive mountain airport.
• Watch: Drukair occasionally adds seasonal frequencies on the BKK–PBH route ahead of peak festival periods. A new morning departure would meaningfully improve the connection window for travelers arriving from Europe the previous evening.
