Wi-Fi is available on Singapore Airlines flights between Hong Kong and San Francisco once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members, although Economy Class and Premium Economy Class members should add their membership number to the booking at least 1.5 hours before departure. Paid plans are available for non-members. The connection is suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

On both sectors of this route, Economy Class seats offer a 32-inch pitch with up to 19-inch seat width, and Premium Economy Class seats, where available, offer a 38-inch pitch with up to 20-inch seat width.

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.

Lounge Access Eligibility
Cabin Class: Complimentary for Suites, First, and Business Class passengers. Premium Economy and Economy travellers do not have access unless they hold eligible status.

Frequent Flyer Status: PPS Club and KrisFlyer Elite Gold (or Star Alliance Gold) members have access regardless of cabin class.

The 'Next Segment' Rule: Eligibility is based on the flight immediately departing that airport. For example, if you fly Economy from Hong Kong but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

Singapore Changi Airport offers a dedicated free transit tour for passengers with sufficient layover time, normally requiring at least around 5.5 to 6 hours between flights. This lets you briefly explore highlights of Singapore before returning comfortably for your onward sector.

If you prefer to stay airside, you can enjoy indoor gardens, themed rest areas, quiet zones, and family-friendly play spaces spread across the terminals. Selected terminals also feature attractions such as kinetic art installations, movie screenings, and relaxation corners.

For a longer break, you may choose to book an airport hotel or use spa and shower facilities within the transit area to refresh before your long-haul flight to San Francisco. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Hong Kong follows Hong Kong Time (HKT), which is UTC+8 and does not observe daylight saving time. San Francisco 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 San Francisco is 16 hours behind Hong Kong during Standard Time and 15 hours behind during Daylight Time.

Yes, your baggage will typically be checked through to San Francisco International Airport when flying from Hong Kong via Singapore on a single booking with Singapore Airlines.

Through-Check Conditions
For your bags to be sent directly to your final destination, the following general conditions must be met:

Single Itinerary: Both flight segments (Hong Kong–Singapore and Singapore–San Francisco) must be under the same booking reference or PNR.

Layover Duration: Your connection in Singapore must be less than 24 hours. If your layover exceeds 24 hours, it is considered a stopover, and you will typically be required to collect your luggage and re-check it for your onward flight.

Partner Airlines: If your onward flight from Singapore to San Francisco is operated by a partner airline, Singapore Airlines has through-check agreements that usually allow your bags to be tagged to your final destination.

You may be able to plan a stopover in Singapore on your Hong Kong–San Francisco trip, 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.
