Big Push on NYC today from Europe. There are fares available on Swiss Airlines from London via Zurich outbound and Geneva inbound to New York over the Christmas period. Usually fares at this time are much higher as you can see in the other deals as they are always unavailable during Christmas and new year. 

Swiss operate A300s on this route and offer excellent service. These flights will also accrue airmiles with Star Alliance. Booking is through Momondo. 

Christmas in New York is something to experience. From the tree at Rockefeller centre, ice skating in Central Park to some pretty serious shopping. You won’t find a better fare to get there from London this year.
