Flights to USA from Thailand — Routes, Airlines, THB Fares | 2026

Flights to USA from Thailand: the SiamFlights catalogue lists 4 routes from 1 Thai airports, flown by Thai Airways, Cathay Pacific, Korean Air, EVA Air and All Nippon Airways. This is a cluster C — Thai diaspora / VFR corridor. Local currency USD; fares are shown in THB.

Visa & currency — USA

We record 0 visa rule(s) for a Thai passport travelling to USA, where the local currency is USD, across 4 corridors from 1 Thai airports in our catalogue. Visa rules attach to the passport’s nationality, never to the airline or the fare.

Thai passport to USA: B1/B2 visa required. Keep passport valid ≥6 months. Local currency USD. Verify current rules at mfa.go.th before buying a ticket.

The fare is in baht; the trip is not. Every price here is quoted in THB while ground costs at the destination are in USD. Exchange spread and card conversion fees are the line most often omitted when comparing a whole-trip budget. Choosing to be charged in baht on a foreign terminal means accepting the merchant’s rate, which is almost never better than your issuing bank’s.

Companions on other passports sit under other rules. A family or group holding different nationalities can face entirely different requirements on the same flight to USA. Check each person separately before booking as a group, and do not infer from what a group member experienced before — requirements change between two trips.

Routes to USA from Thai airports

Our catalogue holds 4 corridors from Thailand to USA, leaving 1 Thai airports for 4 destination airports, roughly 41 departures a week combined, block times 17.5–18.5 hours. 5 carriers appear across those corridors. Local currency is USD while every price here is quoted in THB.

Frequencies here are estimates of the standard schedule. They describe the shape of the network, not the timetable for your dates. Carriers add and cut rotations seasonally and some corridors operate only in certain months. Use these to compare which routes are dense and which are thin, then confirm your actual dates against the airline’s schedule.

Airlines flying to USA

5 carriers serve USA corridors in our catalogue, with baseline allowances from 30 to 30 kg. Of the 4 we hold an airline row for, 0 are registered in the destination country, 1 in Thailand and 3 are third-country carriers.

Carrier nationality changes what you are owed. Thai Airways are Thai-registered. Passenger rights are set first by the country the flight departs from, and in some jurisdictions — the EU and UK notably — the carrier’s nationality extends cover to inbound flights as well. Choosing an airline therefore has a genuine legal consequence, not only a service and price one.

Third-country carriers usually mean a connection. Cathay Pacific, Korean Air and EVA Air are registered neither in Thailand nor in USA. Travelling with them normally routes through their own hub, which typically adds journey time and reduces the fare. What must be checked is the transit rule of the hub’s country: some nationalities need a transit visa even without leaving the sterile area.

USA corridor character

Corridors to USA average about 17.8 hours of block time, split 4 long-haul (7h+), with 4 flagged as labour/migrant routes. The lowest fare we have recorded is ฿18,474 on BKK–JFK. 5 carriers appear across those corridors. Combined frequency is roughly 41 departures a week.

Routes to USA from Thailand are a cluster C — Thai diaspora / VFR corridor. The average block time is about 17.8 hours. 4 of them are labour-migration or diaspora corridors. The lowest fare our feed returned across this country’s corridors is about ฿18,336 on BKK-JFK (it moves with season). Compare month-by-month fares for each city pair on the route pages.

A country low is not your corridor’s price. The figure comes from one route in this group, and other corridors to USA can sit at an entirely different level because distance and capacity differ. It is useful for comparing country against country, not for budgeting a specific city pair. Take corridor-level pricing from that route’s own guide.

Best time to book

Across the 8 months we captured on corridors to USA, the cheapest reading was Dec 2026 at ฿12,540 and the dearest Mar 2027 at ฿17,516 — a 40% spread. These are observations, not forecasts. We hold 4 corridors from 1 Thai airports to 4 destination airports.

Fares to USA are cheapest outside Thai school holidays, Songkran and New Year. Book 4–8 weeks ahead; compare months in the route table and city-pair pages.

Widen your dates before hunting discounts. On international corridors, moving the departure by one or two days usually does more than switching airline or waiting for a sale, because the price tracks the seats left in each bucket on that specific day. If the dates are fixed, the remaining lever is booking earlier — and that only bites on corridors where capacity tightens seasonally.

A cheap non-changeable fare has a hidden cost. The lowest fares usually carry no-change, no-refund conditions. If your documents, visa or schedule are not yet settled, the saving is routinely smaller than the replacement ticket you will buy when something moves. The safe order is paperwork first, price lock second.

Departure airports for USA

Corridors to USA depart from 1 Thai airports in our catalogue, each with a different route count and frequency — which feeds directly into the fare and into the options you have when a flight is cancelled. Local currency is USD while every price here is quoted in THB.

• Bangkok (BKK) — 4 routes, ~41×/wk

The departure airport changes both the price and the fallback. An airport with more routes and higher frequency gives you more options when something breaks, not merely a lower fare. Choosing between two, read weekly departures alongside price: a slightly cheaper seat on a twice-weekly corridor can become very expensive the moment the plan changes.

Each airport page carries the full network. The links above lead to airport pages listing every direct corridor from that airport, not only those to USA. That is useful when comparing where to depart from, or when looking for a fallback routing through another regional hub.

Positioning into Bangkok is an option worth thinking through fully. If you are outside the capital and direct service to USA from your nearest airport is thin or expensive, flying into Bangkok and connecting internationally is often cheaper. The condition that matters is keeping the whole journey on one ticket. Split it and you absorb the connection risk, a second baggage charge and a fresh check-in yourself.

Passenger rights on flights to USA

We hold 4 corridors from 1 Thai airports to 4 destination airports. Departures from Thailand to USA fall under Thailand CAAT; the return falls under US DOT — Aviation Consumer Protection. What you are owed changes with the direction of travel and the operating carrier’s nationality — not with the fare you paid or the cabin you sat in.

There is no US EU261. US DOT — Aviation Consumer Protection governs refunds when a flight is cancelled or significantly changed, tarmac-delay rules, and compensation for involuntary denied boarding — but there is no European-style cash schedule for delay or cancellation. Expecting a delay payout on a US itinerary is one of the most common misreadings of the rules. Departures from Thailand remain with Thailand CAAT.

Baggage and delay are governed by different instruments. If a bag is lost or arrives late on an international journey, the basis of claim is the Montreal Convention 1999, which applies where both the origin and destination states are parties. Its ceilings are denominated in SDR and revised periodically, so only the current figure is citable. The practical consequence is that the two claims are independent: having no delay-compensation right does not remove a baggage claim, and the report should be filed at the baggage desk before you leave the airport.
