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. In Singapore, eligible customers may be able to use facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), and the KrisFlyer Gold Lounge.

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

Singapore Changi Airport offers a wide range of ways to spend your layover, from themed gardens and art installations to resting areas and showers. If you have at least 5.5 to 6 hours between flights, you may be able to join a free transit tour into the city, subject to the airport s current programmes and requirements. Shorter layovers can be enjoyed airside with amenities such as quiet zones, children s play areas, and entertainment spaces. Your time at Singapore Changi Airport is more than just a wait — it s an integral part of your journey.

Kolkata follows India Standard Time (IST), which is UTC+5:30 and does not observe daylight saving time. San Francisco follows Pacific Time, which is UTC-8 during standard time (roughly November to early March) and UTC-7 during daylight saving time (roughly March to early November). This means San Francisco is 13.5 hours behind Kolkata during Pacific Standard Time and 12.5 hours behind during Pacific Daylight Time.

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

Single Itinerary
Both flight segments (Kolkata–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 Kolkata–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.
