Special Meals
We offer a wide selection of special meals to meet different dietary needs and preferences. These should be requested before departure through your booking, as they are prepared specially for your flight.

Book the Cook
On eligible sectors and in selected cabins, you can pre-order from our Book the Cook service, choosing from a wider menu so your preferred main course is reserved for you on board.

Beverage Service
Throughout the journey you can enjoy a range of hot and cold drinks, including juices, soft drinks, teas, coffees, and a curated selection of wines and spirits. Our signature Singapore Sling is also available on board.

Wi-Fi is available on Singapore Airlines flights from London to Hanoi once the aircraft is above 10,000 feet.

On aircraft equipped with First Class or Suites, these cabins also offer fully flat beds.

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

At Singapore Changi Airport, longer layovers can be used to join an official transit city tour when available, which typically requires at least a 5.5 to 6-hour connection. For shorter layovers, you can enjoy airside attractions such as indoor gardens, quiet rest zones, and family-friendly play areas. Many travellers also use the airport"s seating, shower facilities, and transit hotels to refresh between flights. Your time at Singapore Changi Airport is more than just a wait — it"s an integral part of your journey.

London operates on Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) roughly from late March to late October. Hanoi follows Indochina Time (UTC+7) year-round and does not observe daylight saving. This means Hanoi is 7 hours ahead of London in winter and 6 hours ahead in summer.

Yes, your baggage will typically be checked through to Noi Bai International Airport when flying from London 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 (London–Singapore and Singapore–Hanoi) 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 Hanoi 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 London–Hanoi 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.
