What is the cost of plane tickets to Bangkok, Thailand from New York City?

Cost is usually based on when you go. Are you leaving during the New Year period or sometime in September. You give very little information and really you should do some research online. You can go to any airlines which flies to Southeast Asia and check the price based on when you want to leave. A few airlines are Eva which flies out of Newark, Northwest/Delta, United, China Air, Cathay Pacific and look to see if they have any special promotions also. You also have those travel websites like a href="http://www.kayak.com" rel="nofollow"http://www.kayak.com/a just enter JFK to BKK .I would give a rough guess of somewhere between $1,000 to $1,500.
