Most flights from Seattle to Thailand connect via Singapore Changi Airport, which is designed to make transit time comfortable and engaging. For shorter layovers, you can enjoy themed gardens, art installations, rest areas, and a wide choice of dining and shopping right inside the terminals.
If your layover is longer, you can consider using a transit hotel, visiting a lounge, or exploring attractions such as indoor greenery and entertainment zones without leaving the airport. Facilities like showers and quiet zones help you freshen up between flights.
Whatever your connection length, try to allow a little time to walk, stretch, and experience the airport's highlights. Your time at the airport is more than just a wait — it's an integral part of your journey.

Thailand operates on a single time zone, Indochina Time (UTC+7), and does not observe daylight saving time. Seattle uses Pacific Time, which is UTC-8 in winter and UTC-7 in summer.
From roughly November to March, Bangkok and Phuket are 15 hours ahead of Seattle. From roughly March to early November, the difference is usually 14 hours ahead, when Seattle is on daylight saving time.
Always check the exact local times for your travel dates, especially around the start and end of daylight saving in the United States.

Yes, your baggage will typically be checked through to your final destination in Thailand when flying via the layover airport on a single booking with Singapore Airlines, provided both flight segments are under the same booking reference (PNR), the connection is under 24 hours, and, for partner-operated onward flights, a through-check agreement is in place.

You may be able to plan a stopover at the layover city on your journey to Thailand, subject to your ticket conditions and availability. When booking, you can search for multi-city options or speak with our customer service team or your travel agent, who can advise whether a stopover can be added to your itinerary.
