What is the cheapest option to travel to New York, USA from Singapore?

I plan to travel to New York USA together with my wife and my little son. But budget is a concern and hoping you guys can help share this knowledge or any airline which is affordable or least expensive to travel?

you might want to try www.farecompare.com or www.kayak.com
They should give you some idea on what the various fares are.

if you have a local travel agent they will tell you of any inside deals that they know of...

Well, one possibility is to stay for free at people's homes. You would only pay for your transportation, and you would probably contribute to the cost of meals, but that is very, very cheap.

To do so check out

www.couchsurfing.com

this website connects people all over the world who are traveling--basically you sign up to find hosts, and in return, if some traveler is stranded near you in the future you open your home to them.

It's an amazing website.

travel by airplane it is cheaper i take that trip every year with my son and get your ticket on priceline.com make sure you go to the part that say name your own price u can get up to 40% off
