There are some amazing airfares to Europe right now from the NY area starting at $426 to Norway, $481 to Denmark and higher for other locations. See this post from Just Another Points Traveller with more info on prices to other locations.
The flights are via Air Canada, United or Norwegian Air (depending on the route) valid for travel from October 26th – December 11th or December 25th – February, 2015. You might have to overnight in Toronto for the Denmark flights but you can also think of this as a way to fly to Toronto AND Denmark for just $481!!
The best deal here though is the non-stop United flights from Newark to Norway for only $426! If you interested in skiing, this is a great time to ski Norway – see below for an idea of availability.
I have no idea how long these fares will last, so act fast! If you book via United.com you have 24 hours to cancel if you change your mind.
