Interesting! While the idea definitely offers advantages, I'd be keen to know what changes would have to be done in the Departure Control Systems (DCS). There needs to be connection to Customer Management (CML), Reservations (RES), Ticketing (TKT), Payment (PAY), etc...

I was employed with Amadeus Data Systems for more than 10 years, have left during COVID period.

This sounds like a big effort. I wonder how Lufthansa pulled this off in 2021...
