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.

With a layover at Singapore Changi Airport, you can enjoy gardens, themed rest areas, and a wide range of dining and shopping options without leaving the terminal. For longer connections of around 5.5 hours or more, you may consider an official transit tour into the city, subject to eligibility and timing.

Shorter layovers are easily filled with airport attractions such as observation decks, relaxation zones, and family-friendly play areas, as well as opportunities to freshen up between flights. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

At Istanbul Airport, eligible Singapore Airlines customers can access partner lounges before departure, subject to their cabin class or frequent flyer status. These lounges offer comfortable seating, refreshments, and quiet spaces to relax or work before boarding your flight to Singapore.

For a single Singapore Airlines booking from Istanbul to Surabaya, we will usually check your baggage through to your final destination, so you do not need to collect it during your layover at Singapore Changi Airport. Your baggage tag and boarding passes will confirm the final routing of your bags.

Istanbul follows Turkey Time (UTC+3) all year, without daylight saving changes. Surabaya follows Western Indonesia Time (UTC+7). This means Surabaya is 4 hours ahead of Istanbul throughout the year; for example, when it is 12.00 in Istanbul, it is 16.00 in Surabaya.

When you arrive at Juanda International Airport, you will proceed through immigration and baggage claim before entering the public arrivals area. Ground transport options include taxis, app-based car services, and pre-arranged hotel transfers. It is best to check local information in advance for the latest guidance on transport and services.

Visa and entry requirements for Indonesia depend on your nationality, travel purpose, and length of stay. We recommend that you check with the nearest Indonesian embassy or consulate, or consult official government sources, before your trip to ensure you have the correct documents.

Surabaya is warm and humid throughout the year, so light, breathable clothing is recommended. A compact umbrella or light rain jacket is useful, especially during the wet season from November to March. Comfortable footwear is helpful for walking around markets, malls, and waterfront areas.

For your Singapore Airlines flight from Istanbul to Surabaya via Singapore, we recommend arriving at Istanbul Airport at least 3 hours before departure. This allows enough time for check-in, security, and passport control, especially during busy travel periods.
