Book a LON-SIN roundtrip that costs less

Airlines often price the London to Singapore round-trip below the one-way, so you buy the pair and never fly the return. That is a spare return, a form of throwaway ticketing, and nothing is skipped mid-ticket: your checked bag and your outbound are unaffected. When the fare allows it, you can also reschedule or cancel the extra return.

Add an extra destination after Singapore

A multicity ticket, London to Singapore plus a later journey to or from a third city, sometimes prices below the plain one-way. You fly to Singapore; the second journey is a spare multicity you are free to drop, reschedule, or fit into a later trip. As with a spare return, the spare part is a whole journey on a later date, so nothing is skipped on the day and you can check a bag.

Fly to a cheaper city and stop in Singapore

A ticket to a city beyond Singapore, routed through it, sometimes costs less than the Singapore ticket itself. You get off at the layover and skip the last flight, a hidden city (or skiplagging). It is the one method here that leaves part of the ticket unflown, so travel with a carry-on, and it cannot be used on a round-trip: a missed segment cancels everything after it. Airlines tend to curb this practice, avoid doing it too often.

If you have other trips coming up, try combining them with the Singapore one. Our multisearch engine searches several trips at once and finds ticket arrangements that cost less than the sum of their parts, such as nested or back-to-back tickets. The other trip can be to Singapore again or somewhere else entirely, and it can be months away.

Questions about saving on flights to Singapore

Can I buy a round-trip to Singapore and not fly the return?

Yes, that is a spare return: nothing on the ticket is cancelled, you simply forfeit the return. On this route the round-trip priced below the one-way on a good share of searches, saving 5–15%.

Is a hidden-city ticket safe on flights to Singapore?

Safe enough with two rules: carry-on only, since a checked bag travels to the ticketed destination, and not too often, since airlines curb it. On this route a hidden city ticket routed through Singapore priced below the Singapore fare on most searches, saving 5–15%.

Can I use a hidden-city ticket on a round trip to Singapore?

Not on a plain round-trip: skipping a segment cancels everything after it, so you would lose the return. What works is a hidden return, one multicity ticket from London to Singapore and then from Singapore to a third city routed through London, where you get off.

Is an open-jaw ticket cheaper than a one-way to Singapore?

Sometimes. A multicity ticket with a later journey to or from a third city, a spare multicity, can price below the plain one-way, and since the unused journey is on its own date you can check a bag. On this route it did on a minority of searches, saving 5–15%.
