Fares from London to Singapore (GBP)
Singapore is a year-round destination with a hot, humid climate all twelve months, so fares track school holidays and events more than weather. The dearest weeks are the Christmas/New Year peak, the July–August summer holidays, and Chinese New Year (late January or February). The table below shows when the route is busiest. We no longer print per-month fare estimates here, because they were never measured.
| Month | Typical return (economy) | Demand |
|---|---|---|
| January | — | high (Chinese New Year) |
| February | — | high |
| March | — | medium |
| April | — | medium |
| May | — | medium |
| June | — | medium-high |
| July | — | high (summer holidays) |
| August | — | high |
| September | — | medium (F1 weekend spikes) |
| October | — | low-medium |
| November | — | low-medium |
| December | — | very high (holidays) |
We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Non-stop (about 13 hours from Heathrow):
- Singapore Airlines — multiple non-stops a day from Heathrow, consistently top-rated economy; usually the fastest scheduled time.
- British Airways — non-stop Heathrow → Changi, typically daily on the Boeing 777 or 787.
- Qantas — non-stop from Heathrow on the Airbus A380, continuing onward to Australia.
One-stop (usually the cheapest, about 16–20 hours total):
- Emirates via Dubai — frequent, strong economy, from all three main London airports.
- Qatar Airways via Doha — a short first hop and often the best-value premium economy.
- Etihad via Abu Dhabi and Turkish Airlines via Istanbul — often competitively priced.
Because the one-stop carriers compete hard, they usually undercut the non-stops by £80–£200. If time and comfort matter most, book a non-stop; if price is the priority, a single stop through the Gulf is the sweet spot.
When to book & how to save
- Book 2–4 months ahead for the best balance of price and choice; fares to Singapore rarely improve in the final weeks.
- Avoid the peaks: Christmas/New Year, the July–August summer holidays and Chinese New Year are the busiest and dearest.
- Watch the Grand Prix weekend in September — fares and hotels spike sharply around the night race, so book well ahead or dodge those dates.
- Consider a stopover: a one-stop through the Gulf can be cheaper and lets you break the journey, which many travellers prefer over 13 hours in one go.
- Compare all-in prices including bags: full-service and Gulf carriers usually include 25–30 kg to Singapore, but the cheapest “light” fares may not.
Arriving in Singapore
All flights land at Changi (SIN), about 20 km east of the city and regularly rated the world’s best airport. The cheapest way into town is the MRT from Changi station (change at Tanah Merah), which reaches the centre in around 45 minutes for well under £1.50; a metered taxi to downtown costs roughly £12–£18, and the Airport Line runs late into the evening. Give yourself time to enjoy the terminals — Jewel’s indoor waterfall and gardens are worth arriving early for.
