Delta is offering incredibly discounted fares from New York to Sydney Australia. The Flight Deal found that fares through November 30, 2016 are pricing out at just $675 on Delta (although there might be some partner flights mixed in there).
While this is a great fare to Sydney, keep in mind that it might require two connections, possibly in Atlanta/Detroit/Minneapolis and Los Angeles. The layovers are pretty short though. On the return, it looks like there is the possibility for just one layover at Los Angeles. You also must stay for at least 10 days – which I recommend doing anyways if you are going that far since there is so much to see and do! To find the best price, you can use Delta.com and make sure to select the “flexible” dates option. These $675 fares are not available every day, so you’ll need to be slightly flexible.
Australia is one of my favorite countries and I absolutely love Sydney as I had the opportunity to live nearby on the beach for 6 months awhile ago! If you have the opportunity to go, I highly suggest it! And you will rarely find prices cheaper then these.
