How Many Miles to Fly to Thailand? (2026)

How many miles does business class to Thailand cost?

A one-way business-class redemption to Bangkok (BKK) costs anywhere from about 68,000 to 115,000 miles, and the gap between programs is wide enough that picking the right chart changes the price by tens of thousands of miles for the same seat.

Air Canada Aeroplan prices the route at 102,500 miles one-way as of its June 1, 2026 chart update, up from 87,500 miles, since Los Angeles-Bangkok routings fall in Aeroplan's 7,501-11,000-mile North America-to-Asia distance band (Upgraded Points, 2026). ANA Mileage Club's Star Alliance partner chart prices a US-Bangkok round trip at 136,000 miles (about 68,000 one-way), while ANA's own metal to Southeast Asia can run 100,000-115,000 miles round-trip in low season (The Points Guy, 2026). Singapore KrisFlyer sits at the expensive end, 107,000-115,000 miles one-way for the same cabin (The Points Guy, 2026).

Before committing miles to any of these, it's worth checking what the exact dates and cabin actually cost in miles on the award calculator - published charts set the floor, but availability tier and season both move the real price.

Why isn't there a nonstop flight, and why that matters for your miles

No airline has flown nonstop between the mainland US and Thailand since Thai Airways retired its Bangkok-Los Angeles and Bangkok-New York Airbus A340-500 routes in 2015, because the ultra-long-haul flights lost money even with a premium cabin on board (Simple Flying, 2026).

That single fact reshapes every mileage decision for this trip: Thai Airways' own Royal Orchid Plus award chart prices a Bangkok-North America Royal Silk seat at 90,000 miles one-way, but that number describes a zone rate on a route Thai doesn't currently fly - redeeming it means routing through Bangkok itself, Tokyo, Seoul, or a European hub on a Star Alliance partner instead of a single nonstop segment. United MileagePlus has unusually strong access to Thai Airways' own award space for the connecting portion of these itineraries, more consistently than other Star Alliance programs (LoyaltyLobby, 2026), which is why United and Aeroplan both show up ahead of Thai's own program on most searches originating in the US.

What does business class to Bangkok cost in cash?

Round-trip business class from Los Angeles to Bangkok on carriers like Thai Airways, Cathay Pacific, and Emirates typically runs $3,000 to $7,500 per person, with anything at or below $3,000 considered an exceptional fare and January, February, and November the cheapest months to fly (BusinessClassSignal, 2026).

From London, private fares start around £2,121 round-trip, though publicly listed business fares more commonly run £3,000-£4,000 for the roughly 11.5-hour Thai Airways or British Airways routing (Travel Business First, 2026).

Worked example: buying the miles vs. paying cash

Take the cheapest chart for this route, Air Canada Aeroplan's business-class Bangkok award: 102,500 miles one-way, 205,000 miles round-trip, for a Star Alliance partner routing with one connection (Upgraded Points, 2026).

At MileMarketplace's live Aeroplan price of $150 per 10,000 miles, 205,000 miles costs $3,075. Add MileMarketplace's 5% service fee ($153.75) and the all-in miles cost is $3,228.75, before Aeroplan's flat CA$39 (about US$28) partner-booking fee per passenger and whatever government-imposed taxes apply to the specific routing - Aeroplan itself doesn't add carrier-imposed fuel surcharges (The Points Guy, 2026). Call it roughly $3,260 plus routing-dependent taxes.

Against a $3,000-$7,500 cash fare for the identical seat, that miles price beats the upper half of the range clearly and roughly breaks even against the cheapest cash sales - which is exactly why it's worth running your own dates through the award calculator instead of assuming the miles route always wins.

Which program is the best value once you factor in price?

Miles needed is only half the equation - what those miles cost to acquire matters just as much. On MileMarketplace, Aeroplan miles run $150 per 10,000 (about 1.5 cents each), making its 102,500-mile Bangkok redemption the cheapest all-in option among the programs with live offers. Singapore KrisFlyer costs more per mile ($165 per 10,000) and requires more of them (107,000-115,000), so it lands well behind Aeroplan on total dollars despite similar seat quality.

Cathay Pacific's Asia Miles chart is priced by distance from Hong Kong rather than from the US, so a Hong Kong-Bangkok segment alone costs 27,000 miles in Cathay's cheapest business band under its post-May-2026 chart - useful mainly if you're already routing through Hong Kong, not as a standalone US-Bangkok solution. ANA and Thai Royal Orchid Plus both have real award charts worth checking, but neither currently has live sell-side offers on MileMarketplace, so they're better suited to travelers who already hold a balance in those programs.

What if you're short on the miles you need?

This is the gap MileMarketplace is built for: buy just the miles you're short, in the program with the best chart for your specific route, instead of transferring flexible points at a worse ratio or settling for a connection you didn't want. If comparing charts and buying the difference still feels like more work than you want to take on, MileMarketplace's team will also book the flight for you directly at the same low price - useful if you'd rather hand over the dates and let someone else find the award space.
