There are three airlines offering flights to Singapore. The most direct route isn’t necessarily the cheapest – being flexible is key to finding the lowest airfare rates. For example, try searching by month to see the best time of the week to fly.
You can use the filters on your search to see more flights and find cheaper rates – Singapore has more than one airport. So if you don't need to fly into Singapore Changi International Airport, it's worth checking your other options. The 10879 km flight usually takes about 20 hrs 15 mins.
During this peak season, accommodation prices often increase too, so it's best to book early. Or you could keep your fingers crossed and hold out for a last-minute deal.
