Cheap fares across the Atlantic are becoming the new norm with low cost carriers launching and the US airlines trying to compete with occasional flight sales. Taking advantage of a bargain fare on Norwegian will get get you a no-frills service to your destination potentially on a 737, not very glamorous.
A much more enjoyable way to travel to Europe is onboard the Emirates A380 from JFK to Milan. They are currently running a promotion with lots of dates available up until December for $398 round trip based on two people travelling. It is still a very reasonable $448 if you are travelling alone.
These are full service flights with award winning service aboard their flagship A380 aircraft. Where there won’t be any charges for food and drinks and certainly not for a glass of water. This really is one of the best ways to travel in economy across the Atlantic from the east coast.
Once in Milan Northern Italy is at your finger tips or explore Europe with one of low cost airlines who can get you pretty much anywhere at a reasonable price.
