Heading back from Italy mid-summer. Have two options (both airports will be somewhat convenient for me, as I can manipulate my travel without any hassle for both). NAP-EWR in 767-3, in PE either bulkhead or second exit row (travelling family of 4). FCO-EWR PPP bulkhead middle. Miles are not an issue, as wife and I have over a million to burn, though PPP a little over 100k each and PE 70k (we're flying over in J on plus points upgrade).

Even though we have miles, is it a significant upgrade into 777 PPP? Or do we suck it up for the PE seats out of NAP?
