For flights between Penang and Surabaya, the weight concept applies. Checked baggage allowances are: Economy Class (25kg for Lite and Value fares, 30kg for Standard and Flexi fares) and Business Class (40kg). Each checked bag must not exceed 32kg. For cabin baggage, Economy Class passengers may bring 1 piece up to 7kg, while Business Class passengers may bring 2 pieces, each up to 7kg. The final allowance for your journey is shown on your e-ticket, and KrisFlyer Elite Gold and PPS Club members enjoy additional allowances.

Wi-Fi is available on Singapore Airlines flights once the aircraft is above 10,000 feet on this route. It is free and unlimited for KrisFlyer members; Economy Class members must add their membership number to the booking at least 1.5 hours before departure. Non-members can purchase access plans. The service is ideal for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

On the Penang–Singapore sector operated by the Boeing 737-8 MAX, Economy Class seats offer a 32-inch pitch with up to 19-inch seat width, while Business Class provides a fully flat bed with direct aisle access. On the Singapore–Surabaya Airbus A350-900 sector, Economy Class also features a 32-inch pitch and up to 19-inch seat width, and Business Class offers a fully flat bed with direct aisle access.

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.

Passengers travelling on this route may be able to use facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge at Singapore Changi Airport, depending on eligibility.

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

Singapore Changi Airport is well known for its transit experience, and if your layover is at least 5.5 to 6 hours, you can consider joining one of the official free city tours that introduce you to key sights without the need to plan your own route. For shorter layovers, it is best to stay airside and make use of the airport's many amenities.

Inside the terminals, you will find themed gardens, rest zones, and play areas, as well as shower facilities and transit hotels if you wish to refresh or rest in privacy. There are also quiet seating corners ideal for reading, working, or simply relaxing between flights.

Dining and shopping options are extensive, ranging from quick bites to full-service restaurants and a wide range of retail outlets. Your time at Singapore Changi Airport is more than just a wait — it's an integral part of your journey.

Penang follows Malaysia Time (UTC+8) all year and does not observe daylight saving time. Surabaya follows Western Indonesia Time (UTC+7), also without daylight saving. This means Surabaya is 1 hour behind Penang throughout the year; for example, when it is 15.00 in Penang, it is 14.00 in Surabaya.

Yes, your baggage will typically be checked through to Surabaya when flying from Penang 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 (Penang–Singapore and Singapore–Surabaya) 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 Surabaya 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 Penang–Surabaya 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.
