3 airlines go head-to-head on the LAX–BKK route. Compare seats, lounges, and fares from $3,000.
3 airlines fly business class from Los Angeles (LAX) to Bangkok (BKK), with round-trip fares ranging from $3,000 to $7,500. The average flight time is 17 hours. Thai Airways and Cathay Pacific are the primary competitors on this route. The most affordable fares typically appear in January, February, November.
The seventeen-hour haul from Los Angeles to Bangkok is one of those routes that genuinely separates the serious business class carriers from the pretenders, and right now three airlines are making a compelling case for your loyalty — each with a distinctly different philosophy about what long-haul comfort should feel like.

Cathay Pacific is, frankly, the product to beat on this routing. The Aria Suite rollout brings direct aisle access and a level of privacy that makes seventeen hours feel almost manageable, and the carrier's connection through Hong Kong remains one of the smoothest transit experiences in Asia. The Wing lounge at HKG continues to outclass its regional competitors, and the in-flight dining — particularly the Hong Kong-style congee service at breakfast — reflects a kitchen that understands the difference between airline food and actual food. Suite seekers and travelers who treat the journey as part of the destination should book Cathay without much hesitation. The airline also tends to release competitive fares during November and January, when northern hemisphere demand softens before the Thai high season peaks.
Emirates approaches the same journey with characteristic maximalism. The A380 configuration via Dubai gives you a genuine mini-bar, considerable seat width, and a social atmosphere that some travelers adore and others find distracting. The connection through DXB is longer than Hong Kong, adding real hours to your door-to-door time, but the Emirates lounge network at Dubai is genuinely impressive for travelers who enjoy the spectacle of scale. Foodies and those who appreciate theatrical service will feel at home here, and Emirates frequently prices aggressively in February when Bangkok-bound leisure traffic dips.
Thai Airways occupies a more complicated position. The Royal Silk product on the A350 is comfortable and the staggered lie-flat configuration is perfectly respectable, but the soft product — service consistency, lounge quality at LAX, and catering ambition — lags behind both competitors. What Thai does offer is a nonstop emotional connection to the destination: Thai crew, Thai cuisine, and an arrival into Suvarnabhumi that feels culturally continuous with the journey itself. Value hunters willing to prioritize price over polish, particularly those booking in December before holiday surcharges bite, will find Thai's fares worth the trade-off. For everyone else, Cathay Pacific remains the most complete answer on this route.
