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, longer layovers can be used to join a city transit tour, which usually requires a minimum of around 5.5 to 6 hours between flights. This is a convenient way to see highlights of Singapore before returning for your onward connection to Hanoi.

For shorter layovers, you can stay airside and enjoy the airport's facilities, including themed gardens, rest areas, showers, and play zones. There are also plenty of dining options and shops if you prefer to relax with a meal or browse for gifts. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Yes, at Seoul Incheon (ICN), eligible passengers travelling on Singapore Airlines flights can access the SilverKris Lounge before their departure to Singapore. Access depends on your cabin class and KrisFlyer or Star Alliance status.

If you have a sufficiently long layover, you may be able to leave Singapore Changi Airport to explore the city, subject to local entry requirements. We recommend allowing ample time for immigration, transport, and security checks before your onward flight. Always check visa rules and your boarding time before leaving the terminal.

Seoul follows Korea Standard Time (UTC+9) all year. Hanoi follows Indochina Time (UTC+7) and does not observe daylight saving time. This means Hanoi is 2 hours behind Seoul throughout the year, regardless of the month you travel.

Singapore Airlines flights from Seoul Incheon to Singapore typically arrive at and depart from terminals used by Singapore Airlines at Singapore Changi Airport, where you will also connect to your onward flight to Hanoi. Your exact terminal and gate will be shown on your e-ticket and boarding passes closer to departure.

For most Seoul to Hanoi itineraries on a single Singapore Airlines ticket, our schedules are planned to provide a comfortable connection at Singapore Changi Airport. If you book flights separately or plan to leave the airport, we recommend allowing extra time for security and immigration. Always follow the minimum connection time shown in your booking.

Visa requirements for Vietnam and any transit rules for Singapore depend on your nationality and passport. We recommend checking with the relevant embassies or official government websites before travel, and ensuring your passport has sufficient validity for your trip.

If your Seoul to Singapore and Singapore to Hanoi flights are issued on a single Singapore Airlines ticket, we will usually check your baggage through to Hanoi at Seoul Incheon. You should still confirm this at check-in, and keep your baggage tags and boarding passes until you collect your bags at your final destination.

On arrival at Hanoi, you will proceed through immigration, collect your checked baggage, and then clear customs. After exiting, you will find options for transport into the city, such as airport buses, taxis, and pre-arranged transfers. It is best to confirm local transport and entry requirements before your flight.
