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. Eligible customers may have access to facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge at Singapore Changi Airport.

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 San Francisco but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

If you have a longer layover at Singapore Changi Airport, you can join an official free city tour when available, typically suited for layovers of around 5.5 hours or more, allowing you to sample key sights before your onward flight. For shorter connections, stay airside to enjoy themed gardens, quiet rest areas, and relaxation zones within the terminals. You can also make use of airport hotels, showers, and family-friendly spaces to refresh or rest between flights. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

San Francisco follows Pacific Time, which is UTC−8, switching to UTC−7 during daylight saving time from roughly March to early November. Kolkata follows India Standard Time year-round, which is UTC+5:30. This means Kolkata is 13.5 hours ahead of San Francisco in winter, and 12.5 hours ahead during San Francisco’s daylight saving time.

Yes, your baggage will typically be checked through to Netaji Subhash Chandra Bose International Airport in Kolkata when flying from San Francisco 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 (San Francisco–Singapore and Singapore–Kolkata) 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 Kolkata 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 San Francisco–Kolkata 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.
