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 Singapore Changi Airport, eligible customers may have access to lounges such as The Private Room, SilverKris Lounge (First Class), SilverKris Lounge (Business Class), and 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 Hong Kong but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

Singapore Changi Airport offers extensive facilities for transit passengers, including themed gardens, rest zones, and family-friendly play areas, making it easy to stay comfortable without leaving the terminal. With a sufficient layover, you can also join a free official city tour, which usually requires at least around 5.5 to 6 hours between flights.

For shorter connections, you might enjoy a quiet corner to rest, explore the airport's art installations, or take advantage of shower facilities and dining options in your terminal. Clear signage and frequent Skytrain services connect the terminals to help you move smoothly between gates.

Your time at Singapore Changi Airport is more than just a wait — it's an integral part of your journey.

Hong Kong operates on Hong Kong Time (HKT), which is UTC+8 and does not observe daylight saving time. Hanoi operates on Indochina Time (ICT), which is UTC+7 and also does not observe daylight saving time. This means Hanoi is 1 hour behind Hong Kong throughout the year.

Yes, your baggage will typically be checked through to Noi Bai International Airport in Hanoi when flying from Hong Kong 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 (Hong Kong–Singapore and Singapore–Hanoi) 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 Hanoi 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 Hong Kong–Hanoi 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.
