I'm looking at options for flights USA-TLV in J in a couple of months. One of the options is to connect in FCO rather than taking the nonstop JFK-TLV. The flight USA-FCO would be on DL, and the flight FCO-TLV would be on AZ. I'd have a 4-5 hour layover in FCO depending on the originating gateway in the USA.
If I were to take this option, how much of a headache would it be to try to access the Casa Alitalia lounge that has a shower? I'm assuming that both flights would be on concourse E and that I'd never have to pass passport control since I'd be in transit between two non-schengen countries. Is that a correct assumption?
