It is free and unlimited for KrisFlyer members; Economy Class and Premium Economy Class guests should add their membership number to the booking at least 1.5 hours before departure.

On the Seattle–Singapore and Singapore–Kolkata sectors, Economy Class seats offer a 32-inch pitch and up to 19-inch seat width for comfortable legroom. Premium Economy Class, available on the Seattle–Singapore sector, offers a 38-inch pitch and up to 20-inch seat width. Business Class on both sectors features a fully flat bed with every seat providing direct aisle access, giving you ample space to rest.

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

Singapore Changi Airport offers a range of transit experiences, from themed gardens and art installations to rest areas and nap-friendly seating, making even shorter layovers comfortable. For layovers of at least around 5.5–6 hours, you can consider joining an official free city tour, subject to eligibility and timing.

If you prefer to stay airside, you will find quiet zones, shower facilities, children’s play areas, and a broad selection of dining and shopping options within the terminals. Wayfinding is clear and security checks are efficient, so moving between gates and terminals is straightforward.

For longer connections, you may wish to book an airport hotel or pay-per-use lounge to rest and freshen up in privacy before your onward flight to Kolkata. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Seattle follows Pacific Time, which is UTC−8 in winter and UTC−7 during daylight saving time, typically from March to early November. Kolkata follows India Standard Time (IST), which is UTC+5:30 year-round. This means Kolkata is 13.5 hours ahead of Seattle during Pacific Standard Time, and 12.5 hours ahead during Pacific Daylight Time.

Yes, your baggage will typically be checked through to Netaji Subhas Chandra Bose International Airport when flying from Seattle 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 (Seattle–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 Seattle–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.
