Air Berlin has great fares available from NYC to Berlin. You can grab a round trip flight for just $332, if you travel between December 2016 and April 2017. You will have a stopover in Germany on both legs.
You can search for dates on Momondo or Priceline or even on AirBerlin’s website, although it’s showing a few dollars more in there.
Make sure you use a credit card that will give you the most points, such as Amex Platinum (5x on airfare) or Chase Sapphire Reserve (3x on travel).
