Delta is great because when you land, you are already on the domestic side of the airport. Since I take the train/subway downtown, way cheaper than a taxi or Uber, I do not have to take a shuttle all the way around the airport to the subway: I just take a quick link train and walk a short distance. Easy and fast! Like travel should be.

As I have two connections international flight. Whether the check luggage goes to the final destination automatically, and how many free check luggages need to advice clearly while booking. Since the two code sharing air flight companies provided different information which was very confusion.
