I think I know the answer to this, but want to double check.
Flying from SFO - CDG on Monday, I am currently out of pocket, and won’t have my passport until Sunday AM when I get back home.
Do I have to use Ready2Fly? Or can I just show up at the SFO ticketing counter and then present my passport and ID there for verification? I am transiting through CDG on my way to LHR, so don’t believe I need anything else right?
