Yes, Singapore Airlines provides lounge access to eligible passengers with a layover in Singapore. Your eligibility is based on your class of travel or your KrisFlyer and Star Alliance status, and it is determined by your flight leaving Singapore. Other options, like purchasing a day pass at a pay-per-use lounge, are also available.

With a layover at Singapore Changi Airport, you can join a free city transit tour if you have at least around 5.5 to 6 hours between flights, allowing time to discover key sights before returning for your connection. For shorter layovers, stay airside and explore the airports attractions, including themed gardens, rest zones, and entertainment areas. Your time at Singapore Changi Airport is more than just a wait - it is an integral part of your journey.

When departing from Bangkok Suvarnabhumi Airport for your journey to Seattle via Singapore, eligible Singapore Airlines customers may relax in the SilverKris Lounge before boarding, depending on cabin class or frequent flyer status. Lounge access is determined by the airline, your booking, and your membership tier.

During your layover at Singapore Changi Airport, eligible customers may access the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on cabin class and KrisFlyer or Star Alliance status. Lounge entitlements are based on your onward flight from Singapore.

Bangkok follows Indochina Time (UTC+7) and does not observe daylight saving time. Seattle follows Pacific Time, which is UTC-8 during Standard Time (roughly November to March) and UTC-7 during Daylight Time (roughly March to November). This means Seattle is 15 hours behind Bangkok in winter and 14 hours behind in summer.

Visa and entry requirements for travel from Bangkok to Seattle depend on your nationality and the purpose and length of your stay. We recommend checking with the relevant embassy or official authorities, and reviewing the latest updates before your trip, as regulations can change.

For flights from Bangkok to Seattle via Singapore, we recommend arriving at Bangkok Suvarnabhumi Airport at least 3 hours before your scheduled departure. This allows time for check-in, security, immigration, and a relaxed walk to your boarding gate.

When you connect in Singapore on a single Singapore Airlines itinerary, your checked baggage is typically tagged through to Seattle, and you will receive your boarding pass for the onward flight at check-in where possible. Follow the transfer signs on arrival at Changi Airport and check the flight information screens for your departure gate.

If your layover is long enough and you meet entry requirements for Singapore, you may choose to leave the airport and explore the city before returning for your onward flight to Seattle. Always allow sufficient time for immigration, customs, security, and returning to your gate, and check visa rules in advance.
