1. Unless I am mistaken, there is an AF lounge at IAD, and there is direct access from the lounge to the jetway
2. IAD-CDG-FCO
When arriving in CDG, you are entering both the Schengen area, which is a group of countries between which there are no longer immigration controls and the customs territory of the European Union. There are some differences in the way things are done, compared with the US
- you do not need to pick up your bags and re-check them. They are checked in IAD to their final destination, FCO, where customs agents will determine, based upon the lack of the two green stripes on your baggage tags, that you are coming from outside the EU and whether they decide to submit your baggage to a thorough search
- you need to clear immigration in the terminal you arrive in, CDG2C. You can then walk to the arrivals lounge in the same terminal (3mn), where you can have your clothes ironed, have a shower and enjoy a continental breakfast. I have never had to wait for a shower. Spending your time in the arrivals is a better option than in the departures lounge, which is usually more crowded. You should also keep in mind that the arrivals lounge closes at 2:00 PM.
- you should walk from CDG2C to CDG2F, which is the terminal where your flight to FCO departs from. There are moving walkways, through spacious corridors with a view on the tarmac and aircrafts. Total time should be less than 10mn. You first walk to the TGV station and then on to CDG2F where you will need to clear security. After security, it is a 5mn walk to any gate or the departures lounge.
3. MUC AF lounge
Unfortunately, I haven't used the MUC lounge yet.
Enjoy your FC flight to CDG, it should be quite pleasant
