The airline was once the operator of two of the world's longest non-stop routes between Bangkok and Los Angeles and New York City, but due to high fuel prices, the withdrawal of aircraft, luggage weight limits and rising airfares, the airline abandoned all non-stop US services in 2012 indefinitely.
A aeroliña chegou a operar dúas das rutas sen escalas máis longas realizadas, entre Tailandia e Los Angeles e Nova York, pero debido aos altos custos do combustible e a retirada de avións a compañía abandonou todos os seus servizos sen escalas cara os Estados Unidos en 2012.
