Wi-Fi is available on Singapore Airlines flights between Hangzhou and Istanbul once the aircraft is above 10,000 feet.

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 Hangzhou but have a Business Class onward flight from Singapore, you get lounge access in Singapore only. In Singapore (SIN), eligible customers may be invited to use lounges such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on their cabin and status.

For a longer layover at Singapore Changi Airport, you can join the official free city tour if your connection meets the minimum time requirement, typically at least 5.5 to 6 hours between flights. This allows you to see highlights of Singapore before returning comfortably to the terminal. For shorter layovers, stay airside and explore Changi Airport’s attractions, including indoor gardens, rest zones, and entertainment areas where you can stretch, relax, or freshen up between sectors. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Hangzhou follows China Standard Time (UTC+8) throughout the year and does not observe daylight saving time. Istanbul follows Turkey Time, which is fixed at UTC+3 all year. This means Istanbul is 5 hours behind Hangzhou at any time of year.

Yes, your baggage will typically be checked through to Istanbul Airport when flying from Hangzhou 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 (Hangzhou–Singapore and Singapore–Istanbul) 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 Istanbul 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 Hangzhou–Istanbul 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.
