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 Kolkata but have a Business Class onward flight from Singapore, you get lounge access in Singapore only. In Singapore, eligible passengers may use facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), and KrisFlyer Gold Lounge.

If your layover at Singapore Changi Airport is at least 5.5 hours, you can consider joining one of the official transit tours that take you into the city to see key sights before returning in time for your next flight. For shorter layovers, you can stay airside and explore the airport’s attractions, including indoor gardens, rest areas, and entertainment zones spread across the terminals. Airport hotels and snooze zones offer quiet spaces for rest between flights. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Kolkata follows India Standard Time (IST), which is UTC+5:30 and does not observe daylight saving time. Seattle follows Pacific Time, which is UTC-8 during Standard Time (approximately November to March) and UTC-7 during Daylight Time (approximately March to November). This means Seattle is 13.5 hours behind Kolkata in winter and 12.5 hours behind in summer.

Yes, your baggage will typically be checked through to Seattle-Tacoma International Airport when flying from Kolkata 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 (Kolkata–Singapore and Singapore–Seattle) 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 Seattle 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–Seattle 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.
