I flew from Atlanta to Dallas one time, to get to Europe. To save a few bucks. (while somebody probably flew from New York to Atlanta to Fly to Europe, to save some money)Flew SAS from NY to Norway. It appeared to be one of the only direct flights. All other flights went to Copenhagen first and then to you destination. Which was rather strange since it went from NY to Copenhagen to Iceland or NY to Copenhagen to England or NY to Copenhagen to Greenland or NY to Copenhagen to Sweden...so, in some cases, you flew past where you wanted to go to fly back to where you wanted to go.
But if you fly NY to Iceland, why not use Lux Air?
