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.

At London Heathrow, eligible customers can access the SilverKris Lounge (First Class) or SilverKris Lounge (Business Class) before flying to Singapore. At London Gatwick, eligible customers may use the No 1 Lounge. During your layover at Singapore Changi Airport, eligible customers may access The Private Room, SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or the KrisFlyer Gold Lounge, depending on cabin and membership status.

Singapore Changi Airport is well suited to longer layovers, with attractions such as indoor gardens, art installations, and quiet rest areas. If you have at least 5.5 to 6 hours between flights, you can consider joining the airport’s official city transit tour. For shorter layovers, you can enjoy airside amenities including walking trails, relaxation zones, and a broad choice of dining and shopping. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

London operates on Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) roughly from late March to late October. San Francisco follows Pacific Time, using Pacific Standard Time (PST, UTC−8) in winter and Pacific Daylight Time (PDT, UTC−7) in summer. This means San Francisco is typically 8 hours behind London during the UK winter and 7 or 8 hours behind during the UK summer, depending on the exact dates when each location changes its clocks.

Singapore Airlines operates flights to Singapore from both London Heathrow and London Gatwick on selected services, with onward connections to San Francisco from Singapore. Your departure airport and terminal are shown on your booking confirmation and e-ticket, so please check them carefully before you travel.

For flights from London to Singapore with a connection to San Francisco, we recommend arriving at the airport at least 3 hours before your scheduled departure time. This allows sufficient time for check-in, security screening, and reaching your departure gate in a relaxed manner.

If your London–San Francisco journey is booked on a single Singapore Airlines itinerary and you remain in transit at Singapore Changi Airport, you usually do not need to clear immigration. You simply follow the transit signs to your next departure gate or lounge. If you plan to enter the city during your layover, you must meet the entry requirements for Singapore.
