I'm in Malaga killing a couple hours before I can pick up the rental bike. Restaurant with an outdoor patio just outside the airport, walking distance, still within wifi range. The other objective was to pay for "something" with my credit card, so that hopefully they recognise that I'm here.
The changeover in Paris was, as expected, iffy. They had three customs agents on duty (the rest were apparently on break ... government employees ...) and EVERY person coming in from international travel had to pass through one of those three. Needless to say, the sign saying that there was a "< 15 min" lineup was grossly lying. People were trying to attract the attention of the agents to point out how close their departure time was ... except, everyone was in that situation. I got to the plane 15 minutes after gate-close cutoff time (and 5 minutes before scheduled departure), but they held the plane back, and there were a few more passengers who were even later than that. But ... the arrival at Malaga was at the advertised time.
The covid screening situation was no problemo as long as you had your paperwork in order. Vaccination documents had been pre-submitted via the airline (and it shows on your boarding pass that you have done so), customs agent in Paris (EU entry point) checked that I had them, and there's a checkpoint in Spain to check your QR code, which was very quick. It appears that if you didn't have the QR code, they just diverted you to fill out a paper form, so that addresses how to handle people without smartphones. I'd say they have this process well sorted.
