Flight Time from Los Angeles (LAX) to Bangkok (BKK)

Non-stop, the LAX–BKK sector prices out at 16.32 hours — 13,303 km at 850 km/h plus 40 minutes of taxi, climb and approach. Each stopover adds ground dwell at the hub, so the totals model out to about 19.8 hours for one stop and 25.8 for two.

At 13,303 km, crew and aircraft rotation limits start to shape schedules — expect either a genuine non-stop or a single well-placed technical stop rather than casual connections. The clock moves 15 h forward (UTC−8 → UTC+7), so a morning departure can land well into the local evening.

If fares into BKK spike, the airports tabulated below are the first places to check; each row shows the distance back to Bangkok and the flight time from Los Angeles. From LAX, reaching CNX instead takes about 1.4 h — less airborne time than the 16.32 h non-stop, and the surface leg into Bangkok still has to be won back.

Where a matching calculator page exists (LAX → CNX, LAX → HKT among them) the links are in the Related list below. Ground transfer from the alternative airport back into Bangkok is the catch for arrivals off the LAX service: the 582 km back-offset is time you must win back in fare savings.

A 10:00 departure works out to roughly 17:19 on the clock in Bangkok — the 16.32 h airborne leg plus the UTC−8 → UTC+7 shift. Hotel, meal and transit averages put a Bangkok day at $75 against $268 in Los Angeles — worth weighing against any fare premium for better flight times.

On those numbers Bangkok is the cheaper place to linger — the gap is $193 per day, which over a week funds a second flight. With 15 hours gained eastbound, the 13,303 km out to Bangkok ends in a serious jet-lag bill — plan a quiet first day.
