Flights from Thailand to San Francisco (SFO)

Yes, meals are served on flights from Thailand to San Francisco. On routes such as Bangkok to Singapore and onward to San Francisco, you can enjoy our in-flight dining with multi-course meals inspired by international and regional flavours. A range of special meals can be requested in advance to suit different dietary needs. On eligible sectors and in selected premium cabins, Book the Cook allows you to pre-select main courses created by our International Culinary Panel. Throughout the flight, a beverage service offers hot and cold drinks, including the signature Singapore Sling on most long-haul services.

On flights between Thailand and the United States, our checked baggage allowance generally follows the piece concept, while cabin baggage is based on weight and number of pieces. In Economy Class, you can usually bring at least one piece of checked baggage plus a cabin bag and a personal item within the permitted weight. Premium Economy Class offers a higher checked baggage allowance compared to Economy Class. Business Class includes an even more generous checked baggage allowance, together with additional cabin baggage. Exact allowances depend on your ticket type and KrisFlyer or partner status, so please check your e-ticket or our website before you travel.

Wi-Fi is available on most Singapore Airlines flights from Thailand to San Francisco once the aircraft reaches above 10,000 feet. It is free and unlimited for KrisFlyer members, including those travelling in Economy Class and Premium Economy Class who add their membership number to the booking at least 1.5 hours before departure. Non-members and additional users can purchase Wi-Fi plans onboard. The connection is suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

Across routes from Thailand to San Francisco, you will find Business Class, Premium Economy Class, and Economy Class on the long-haul Airbus A350-900 services between Singapore and San Francisco. On regional flights between Bangkok or Phuket and Singapore, cabins include Business Class and Economy Class, with some flights from Bangkok operated by the Airbus A350-900 that also feature Premium Economy Class. Cabin configurations may vary by aircraft and route.

In Economy Class, you can expect a seat pitch of around 32 inches, with seat widths of up to 19 inches depending on aircraft type. Premium Economy Class offers about 38 inches of pitch and up to 20 inches of seat width, giving more personal space and recline. Business Class provides a fully flat bed with direct aisle access on long-haul Airbus A350-900 services, and generous recline and legroom on regional aircraft. Specific configurations can differ slightly between the Boeing 787-10, Boeing 737-8 MAX, and Airbus A350-900.

Most journeys from Thailand to San Francisco connect via Singapore Changi Airport. For longer layovers, you can explore indoor gardens, walking trails, and attractions such as aquariums and play areas, or, subject to eligibility and timing, join an official city transit tour. Shorter connections are easily filled with a relaxed meal, a shower, and some light shopping in the terminals. Your time at the airport is more than just a wait — it is an integral part of your journey.

Bangkok and Phuket share the same time zone, which is typically 14 hours ahead of San Francisco. During daylight saving time in San Francisco, usually from March to early November, the difference is generally 14 hours. For the rest of the year, it is usually 15 hours. Always confirm closer to your travel dates, as daylight saving dates can vary slightly.

Yes, your baggage will typically be checked through to San Francisco 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 San Francisco, 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.
