FlightLogic pick: Singapore Airlines
Singapore Airlines posts a 8.9 composite — second only to Qatar Airways across all 28 carriers we rate — with the best service score on the route (9.5) and route-topping food (9.2). Book the Cook pre-order dining, consistently excellent crew and the Changi hub experience justify the reputation, and KrisFlyer earning is a bonus for Star Alliance flyers. Qantas is a smart alternative for one-stop Australia itineraries on the same ticket; BA remains the Avios default but trails on product.

Cheapest time to fly London to Singapore
A qualitative guide to when fares on this route are usually lower or higher, based on typical travel seasons — not live prices. Actual fares always depend on your dates, demand and how far ahead you book.

Usually cheapest: May and the September-to-November stretch are usually the cheapest times to fly to Singapore, sitting between the summer-holiday and festive peaks. The equatorial climate varies little through the year, so an off-peak trip loses little in weather terms.
Usually priciest: Fares peak during the UK summer holidays and again over Christmas and New Year, and the Chinese New Year period in January or February can also price firmly. Kangaroo Route demand to Australia adds to the pressure in December and January.
When to book: Three strong carriers keep this route competitive, so setting a fare watch two to four months ahead of shoulder-season dates usually surfaces a sensible deal.
Aircraft on the route
Singapore Airlines uses the A380, A350-900 and Boeing 777-300ER; Qantas operates its A380 through-service to Sydney; British Airways flies the Boeing 787-9.
London to Singapore FAQ
Which airlines fly non-stop from London Heathrow to Singapore?

How long is the flight from Heathrow to Singapore?
Between 12 hours 45 minutes and 13 hours outbound, and a little longer on the return. The route covers roughly 6,758 miles — one of the longest non-stop sectors from London.
Can I fly Qantas just between London and Singapore?
Yes. Qantas sells Heathrow–Singapore as a standalone sector on its QF1/QF2 Kangaroo Route service, operated by the A380 — you don’t have to continue to Sydney. It’s a handy way to fly a fourth airline’s product on the route, and Qantas Frequent Flyer or oneworld partners credit normally.
Which alliance is best for London–Singapore?
Star Alliance, via Singapore Airlines’ KrisFlyer — it’s the top-rated product on the route and earns across the whole alliance. oneworld flyers are covered twice over with BA and Qantas, both of which credit to Avios-adjacent programmes. There’s no SkyTeam non-stop option on the route.
