Among Lufthansa’s current offerings of discounted economy fares, New York – Milan stands out as one of the best deals. Currently, you can book travel between NYC and Milan for as low as $629 with excellent availability all the way out to mid-April 2015.
Looking at Google.com/flights, I can see that the best days to find this low fare are on Tuesday, Wednesday, Thursday and Sunday however there are several pockets where the other days of the week show availability as well.
Additionally to get the lowest possible pricing option, either a minimum stay of 3 nights or Saturday night stay is required, otherwise the fares sneak up into the high $600 / low $700 range.
As is typical for any Lufthansa fare sale that involves USA departures, these flights can be operated by one of LH’s Star Alliance partners that operates in the USA. For this specific offer, I’m seeing Lufthansa, Brussels and United as being options. United even offers a non-stop from Newark to Milan making it perhaps the most efficient option. Otherwise you’ll have the option to connect through Munich, Frankfurt or Brussels.
