It's funny to re-up this thread when the last posts were when I was in college, but nonetheless: we're looking to do this trip (NYC > CPH) next summer and cannot figure out the best course of action. There seems to be only one-two direct flights per day, severely limiting the airline options to Delta or SAS. I could do RT on BA Business Class for <$4,000 for two pax, but there's layovers there and back in LHR (in excess of 3+ hours, carry-on luggage only). Doable? Tough it out for a lower seat class, but a direct flight?
