How do you find cheap flights from Singapore

Be flexible on dates, compare the total price including bags, and set a price alert. The cheapest fares out of Singapore usually show up for a short time, so a tracker or a deal email catches them before you would have searched.

Start with the route, not the date

Open a fare calendar (Google Flights has one) and look at a whole month for your route. A fare that is cheap on a Tuesday can be double on the Friday. Moving a trip by a day or two is the biggest lever you control.

Compare the total, not the headline fare

Low-cost carriers often leave out checked bags, seat choice and meals. Add what you will actually need before you compare against a full-service airline. A fare that looks cheaper can end up the same price or higher.

Check nearby airports and one-ways

For some trips a different arrival airport in the same region is cheaper. Two one-way tickets on different airlines can also beat a return ticket. Check both before you book.

Set a price alert for the routes you want

Google Flights can email you when the price on a route changes. It tracks the routes you pick. It does not tell you about trips you had not thought of.

Use a deal email for the trips you had not thought of

A deal club watches many routes and writes to you only when a fare drops well under its normal price. Halfare does this for Singapore: when a fare out of Changi falls 50% or more below its usual price, we email the dates and a link to book.

Book directly with the airline when you can

Changes and refunds are simpler when you hold the ticket with the airline instead of a third party.

Frequently asked questions

When is the cheapest time to fly out of Singapore?

It depends on the route and the season, and school holidays and public holidays push fares up. Compare a full month on a fare calendar for your route instead of trusting a single rule.

Is it cheaper to book a return or two one-ways?

Sometimes two one-ways on different airlines cost less. Price both ways before you book.

Do price alerts really save money?

They only help if the fare drops while you are watching and you are ready to book. They are free, so set one for every route you care about.

What does Halfare add on top of a price alert?

Halfare is for trips you did not search for. We email only fares that are 50% or more below the usual price for the route, with the dates and a booking link.
