Going to Los Angeles (LA), Las Vegas (LV) and San Francisco (SF)? ESTA For Singaporean going to USA, you need to apply for ESTA (Electronic System for Travel Authorization) aka VISA. Cost: USD14 per pax if you apply via https://esta.cbp.dhs.gov/esta/ Flight Due to the long 18 hours flight to LA, we decided not to comprise our journey experience. Thus, we opt for Singapore Airline (SQ) and transit via Japan. Cost: SGD$2,596 for 2 pax (Economy) Recommendation - Flight tickets seem to be at its lowest when booked between 7 - 9 months before departure date - Check the weather in the city you plan to visit before you book your flight. Weather can make your trip either enjoyable or unpleasant - Tranit at Japan is recommended as the in-flight food menu for both leg (SG -> JP, JP -> LA) have super yummy Jap food to choose from. You can also shop around the Japan Airport to buy more Japan...
