FAQs for booking flights from Seattle to Singapore

  • Is a visa required for entry into Singapore?

    For tourist visits of less than 90 days, you will not need to apply for a visa before flying to Singapore. A visa will only be required for business travel and if you plan to stay longer than the 90-day visa-free limit. However, your passport should have at least six months of validity and two pages of entry stamps.

  • What are the layover options from Seattle to Singapore?

    The layover depends on the airline you’re traveling with. The most popular options on this route include London, for British Airways flights, Dubai for Emirates flights, San Francisco when flying with United Airlines, and Incheon when flying with Korean Air. It is important to look up the transit visa requirements before booking to avoid unnecessary inconveniences.

  • Which benefits do I get when I upgrade to first class?

    A first-class ticket makes your trip a lot more comfortable which is especially important for such long-haul trips. You get way more legroom compared to if you were in economy and the seats can recline to a full 180 giving you a makeshift bed which comes in handy with the complimentary pillow. In addition, the meal selection is different and you get up to five-course meals and a premium selection of drinks including wine, champagne, beer, and spirits. Lastly, you get priority boarding for your flight which allows you to settle before departure.

  • How do I access the city center from Singapore Changi Airport (SIN)?

    The Metro is arguably the best transport option to the city center because it is inexpensive and fast connecting to various destinations around the city. However, there is no direct line to the city center meaning you have to change at Tanah Merah Station, and from there you can access any part of the city center. If you have a lot of luggage, the metro can be quite inconvenient, especially during rush hours. A good alternative would be taking a taxi which will drop you at any location you want and the best part is they have a lot of luggage space.

  • What is the cheapest flight from Seattle to Singapore?

    In the last 3 days, the lowest price for a flight from Seattle to Singapore was S$ 415 for a one-way ticket and S$ 750 for a return.
