TGarza - Thanks for your reply! I probably go twice a year to Boston to see our grandkids, my wife a couple times more than that. Delta is choice #1 because of the SkyClub lounges in both LAX and BOS - but our last trip was on JetBlue, which has excellent LAX-BOS service. We went to the Chase Sapphire lounge at BOS the night of our return flight, and we were VERY impressed by it. I would say on par with Centurion and SkyClubs for sure. (We did not realize until later that it was a one-shot deal as a Priority Pass option for us). It would be interesting to know how crowded they get - we were flying late on New Year's Eve and the whole airport was very quiet. (Which means it counted for 2023 and we still get a visit for 2024 if we need it!). I probably wouldn't get the Chase Sapphire credit card just for their lounge in BOS, but I probably would want my next card to include Priority Pass, if possible, as that would get me a second visit to the Chase Sapphire lounge at BOS each year as well if I need it.
