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 spent joining the official transit tour into the city, which typically requires at least about 5.5 to 6 hours between flights. For shorter transits, you can stay airside and enjoy gardens, rest areas, quiet zones, and entertainment facilities within the terminals. There are also showers, transit hotels, and many dining and shopping options if you prefer to relax before your connection. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

In London, eligible passengers departing from London Heathrow can access the SilverKris Lounge (First Class) or SilverKris Lounge (Business Class), while those flying from London Gatwick may use the No 1 Lounge. During your layover at Singapore Changi Airport, eligible travellers may have access to The Private Room, SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or the KrisFlyer Gold Lounge, depending on cabin and membership status.

When you travel on a single Singapore Airlines ticket from London to Hanoi via Singapore, we usually check your baggage through to your final destination. You can confirm this at check-in in London, where our staff will verify your baggage tags and advise whether you need to collect anything during your layover.

London follows Greenwich Mean Time (GMT, UTC+0) roughly from late October to late March, and British Summer Time (BST, UTC+1) from late March to late October. Hanoi uses Indochina Time (UTC+7) year-round. This means Hanoi is 7 hours ahead of London during GMT months, and 6 hours ahead during BST months.

Visa requirements depend on your nationality, length of stay, and purpose of visit. We recommend checking with the relevant embassy or official government sources before you travel, as regulations can change and may have specific conditions or documentation requirements.

For flights from London to Hanoi via Singapore, we recommend arriving at the airport at least 3 hours before departure. This gives you enough time for check-in, security checks, and to reach your boarding gate comfortably, especially during busy travel periods.

When connecting in Singapore Changi Airport, follow the transfer signs on arrival and check the flight information screens for your gate and terminal. You normally do not need to clear immigration if your baggage is checked through. Our staff and airport signage will guide you between gates, and your boarding pass will show your next boarding time.

Noi Bai International Airport is located outside central Hanoi. On arrival, you will find authorised taxis, app-based transport, airport buses, and private transfer services. Journey times vary with traffic and time of day, so allow extra time if you are travelling during peak periods. Check locally for current options and recommendations.
