Today, while checking in at Florence (FLR) airport for a flight to SFO (via Paris CDG) the agent at the check in desk asked us for the Covid vaccination card. Both my wife and I had it, with all 5 boosters registered so no issue there.
That came to,a surprise to me since I was not asked to show one when I flew out of Rome last July (to SFO via ZRH), which is ironic since both my wife and I got Covid while in Italy so we were fully positive in spite the 4th booster administered 3 weeks prior).
I have no idea if today’s request was a new requirement by Air France, or just Florence airport, or simply the agent did not know what she was doing.
