Long time New Yorker, 1M miler, very loyal to UA. Now a Martha's Vineyard resident. We've flown BOS-EWR-CDG, BOS-EWR-MXP a few times in the last couple of years in economy plus, which we get for free as lifetime gold....It sure adds a lot of time with the extra flight and having a decent interval at EWR for a trouble free connection. Our next trip to Paris will be nonstop on Delta in their Comfort+, their version of UA Economy plus, which has the added benefit of having only two seats (aisle and window) along the sides....so no third party sitting with wife and me. I'm not knowledgeable what other European destinations that Delta has nonstops from BOS other than CDG, AMS, FCO, but there are others.
