Seattle is in the America/Los_Angeles time zone, which is UTC-8 in winter (approximately November to March) and UTC-7 in summer (approximately March to November) due to daylight saving time. Bangkok is in the Asia/Bangkok time zone, which is UTC+7 year-round. This means Bangkok is 15 hours ahead of Seattle in winter and 14 hours ahead in summer.

When you fly from Seattle to Bangkok with Singapore Airlines, you will arrive at Bangkok Suvarnabhumi Airport. This is the main international gateway to the city, offering convenient connections to central Bangkok by rail, bus, private transfer, and other local transport options.

Our schedules are planned to provide a comfortable connection time at Singapore Changi Airport between your Seattle and Bangkok flights. When booking on a single Singapore Airlines itinerary, any available options will meet the required minimum connection time, giving you enough time to transfer gates and enjoy some of the airport facilities.

If your Seattle to Bangkok journey is booked on a single Singapore Airlines ticket, your checked baggage is usually tagged through to Bangkok, and you can remain in transit at Singapore Changi Airport. You should still check your baggage tags at check-in and follow airport signs for transit security and your next departure gate.

Visa requirements for Thailand and any transit formalities in Singapore depend on your nationality and travel history. We recommend checking the latest information with the relevant embassies or official government sources before you travel, and allowing enough time to arrange any required documents.
