Just a quick word of warning. My partner and I just got off a number of Alitalia flights between NA and Italy and domestically in Italy. Just did a quick check of the 777 seatmap (I was desperately looking for one before we left) and I can tell you there seem to be a number of discrepancies between the seat map and reality.

For example, on the flight home we were in 4D & 4H, which are the center seats in Magnifica (not D&E as on the seat map). Also the rear Magnifica cabin is rows 9-11 and not 7-10 as on the seat map. Nothing that would cause a major problem, but somehow refreshingly Italian about the whole thing.

BTW. One quick word of warning....avoid the bulkhead rows in Magnifica (1 & 9 on the actual planes) like the plague. There is significantly less legroom here than in the rest of the rows. For what it's worth there didn't seem to be any recline restriction for the last row either cabin.
