Expedia is the largest online travel site, so I'd try there first. Alternatively, you might find out what airlines offer flights to Fiji & then figure out what ones offer the best rate by checking each of their websites individually.
As a novel idea, you could also try a travel agent...but, the last time I tried one a few years ago, they were much more expensive than going online to get tickets.
Air Pacific is Fiji's # 1 company / not to mention the World's friendliest Airline!!
Come travel in style and enjoy our Fijian hospitality!!Where can I find a cheap ticket to New York?
Yes you can find cheap air tickets on
