More often than not, you might even have to take in two stops on your route. These include Tokyo-Narita (NRT) and Seattle-Tacoma International (SEA) on Japan Air Lines, Tokyo-Haneda (HND) and Los Angeles International on Japan Air Lines, Hamad International in Doha (DOH) and JFK in New York (JFK) on Qatar Airways, and Seoul-Incheon (INC) and Seattle-Tacoma International (SEA) on Korean Air Lines and Alaska Airlines.

As part of the United States’ Visa Waiver Program (VWP), Singaporean citizens can make use of the Electronic System for Travel Authorization (ESTA), which allows them to enter the US without a visa. The ESTA may be applied for online and in most cases is instant, but it is advised to apply for it at least three days before travel. Once approved, it lasts for up to two years.
