Have a wonderful trip! Some people have complained about the seat pitch on DL
's 777s, but I found that it was great for a long flight. I am 5' 7", so not the tallest person in the world (I still have time to grow though!
), but I was very comfortable and would still have been comfortable even if I were taller. I also found the seats to be very comfortable. They were wide, just the right firmness, and were a good shape, so conformed to my body well. The entertainment was fine. A PTV is always nice to have. The service was very atentive, so good, on my flight. The food was also fine. Keep in mind that that is only how I experienced a Delta 777. You might have an even better experience or not as good of one, but I hope it's great. Now, I wish I could tell you if you'll be on a 2-5-2 or a 3-3-3 777, but unfortunately I can't. The only way to POSSIBLY know in advance would be to call Delta tomorrow because I would think that the airline would likely know which plane is flying ATL
the day of the flight. There are a total of eight 777s in Delta's fleet and two of them are in the 3-3-3 configuration. Those two are N861DA/ship 7002 and N867DA/ship 7008. Given that, you have a 75% chance of being on a 2-5-2 777. Unfortunately I can't tell you anything about Alitalia, but I hope that is a great flight too.
