Flying out of Los Angeles LAX
Los Angeles is the West Coast's long-haul anchor and the natural departure point for anything crossing the Pacific. LAX's advantage on India and Southeast Asia routes is directional: westbound itineraries via Tokyo, Seoul, Taipei or Singapore are frequently faster and cheaper from LAX than the eastbound routings a booking site will show you first, because the site is optimising for the shortest map line rather than the actual schedule. Artesia's Little India and the wider Southern California diaspora make this a high-volume corridor where unpublished fares turn over quickly.
What to know before you fly to Bangkok
Entry requirements for US travellers
US passport holders can enter Thailand without a visa for tourism for a limited stay. The permitted length has changed more than once in recent years, so confirm the current allowance with the Royal Thai Embassy before booking a long trip — overstaying carries real penalties.
Best time to go
November to February is the cool, dry high season with the best weather and the highest fares. March to May is very hot. The green season from June to October brings the lowest prices from the US and rain that is usually heavy rather than constant.
Airports and arrival
Suvarnabhumi (BKK) handles international arrivals and is the connecting point for Phuket, Chiang Mai and the rest of Southeast Asia. Don Mueang (DMK) is the low-cost airport — if your onward flight leaves from there, budget properly for the transfer.
Baggage
Every US–Thailand itinerary connects at least once, typically in East Asia or the Gulf. Allowances on the two legs are frequently different, and the domestic Thai leg to the islands is usually the tightest of the three.

Los Angeles to Bangkok — frequently asked questions
Fares on the Los Angeles–Bangkok route vary widely by season and how far ahead you book. We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.
Carriers on this route include EVA Air, Korean Air, Japan Airlines, ANA and Cathay Pacific. Others serve it on one-stop itineraries, and the cheapest is not always a name you would expect — the lowest fare we have tracked here was on a carrier outside that list more than once. Itineraries offer one stop at Taipei, Seoul, Tokyo or Hong Kong, and total journey time runs about 19–23 hours. Which carrier is cheapest changes with the season and the fare bucket rather than staying fixed, which is why we compare them all on every quote.
Plan on 19–23 hours from Los Angeles International (LAX) to Suvarnabhumi International (BKK), including time on the ground if your itinerary connects.

No — every itinerary from Los Angeles to Bangkok connects at least once, with one stop at Taipei, Seoul, Tokyo or Hong Kong. Which connection is best is not just about total time: the length of the layover, whether you change terminals, and whether both legs are on one ticket all matter more than the headline duration. We compare them rather than sorting by price alone.
LAX carries all of the region's long-haul flying, but Southern California has four other airports — Burbank, Long Beach, John Wayne and Ontario — that can be far more convenient for the first leg of a connecting itinerary and are often cheaper. If your trip connects anyway, starting it from the airport nearest you rather than fighting across the basin to LAX is worth pricing.
Every US itinerary here connects at least once, which means the cheapest headline fare and the best trip are often different bookings. Agents can also hold and combine fares across carriers — an open-jaw into one city and out of another — which most consumer booking sites either cannot price or price badly. SkyKaro's agents are reachable 24/7, and nothing is charged until an agent has confirmed the itinerary and the price with you.
