I want to non-rev on Alitalia in Sept to Rome (FCO) from New York. What is the best day to non-rev to FCO. I was thinking on a Saturday. What airport is more favorable for non-rev from New York JFK or EWR? Also what would be a good day for non-reving on a return from FCO to JFK/EWR?--I was thinking leaving FCO on a Monday. Any suggestion would be greatly appreciated.
