I have tried to get this answered a few times in other threads, but because it is a bit strange, it was never answered. I totally understand why. I'm not blaming anyone. Anyway, next summer, with my mom and my brother, I am going to Italy. We are flying into FCO from ATL and back to ATL from MXP. MXP-ATL is going to be operated by a 777 at that point, but is scheduled as 11 hours 10 minutes. The flight is only 4800 miles, so that seems quite long to me. I don't mind the length and I know that the airtime is not as long as the scheduled time (subtract maybe 40 minutes), but why is it scheduled for so long? FCO-ATL, a 250 mile longer flight is scheduled for 10 hours 55 minutes. It is operated with an MD-11.
Also, I was wondering about my seats. Going to FCO, I booked seat 31A. It is on an MD-11. I flew a DL MD-11 a few years ago to BRU and back and did not find it to be the most comfortable aircraft I have ever flown on. It wasn't so terrible, but exactly pleasant for 7-9 hours. Coming back, I booked myself seat 44A. It is an exit row bulkhead with a window! It is on the 777. I flew a DL 777 this summer from CDG to ATL and it was very comfortable, in just a normal Y seat. Oh, by the way, if you are wondering why we already have tickets, it's because we needed to get frequent flyer tickets and they sell out quickly to Italy. In fact, our original plan was to fly into MXP and out of FCO, but when we called 331 days in advance of our return date (maximum time ahead allowed), they had already sold out the FF seats on one or both of those flights, so had to reverse our itinerary. That was fine, because nothing else was planned. Anyway, thank you so much for your help! I appreciate it a lot!

10 hours 55 minutes and 11:15 are not far apart, and considering the difference in mileage (250), we can assume that the times given are correct. I trust you checked the both flights so that they originated ATL.
Why the longer time? Maybe the departure and arrival times are different, which could mean longer taxi - and hold times. It is also possible that the mileage given is a standard mileage but the actual routes are different (11 hours IS quite long for that mileage). Was the info for both of the flights for the same date (time of the year)?
I know this didn't help. But more questions/answers might resolve the puzzle.

Quite similar to what FFlyer said, the long flight time could be based on other factors than the distance such as taxi time, headwinds, and such. Something else to consider could be the flight's performance history. It could be possible that a flight could take chronic delays due to congestion or other factors. This could be reflected on an updated schedule as a longer flight time. I remember one transatlantic flight running late on almost a daily basis. Finally, the next schedule change simply added time to that route so that the time the flight got in could be close to the scheduled arrival time.

I think if you assume that the flight time is calculated based on the speed of a 767 (ie- it hasn't been recalculated for a 777) and you assume that Delta provides a very generous allowance of groudn time for the taxi in ATL, you've got the difference.
It's a new day. Every moment matters. Now, more than ever.

DeltaSFO is right..this past summer when DL75 was being operated with a 763, scheduled flight time was 10:55 (dep 1045 arr 1540). They probably learnt from experience and padded it for next summer assuming it was a 763, before the switch to the 777 was made. Remember these are just prelim. schedules and will go through some more changes before they are actually finalized....
