Last time i flew through T3 we had to try to get a 2yo to stand on the adult footprints for the wall scanner. It wouldn’t scan him at first. Safe to say it took some time, though the 2yo enjoyed it not sure many other pax did! Operators didn’t know what to do. Hopefully it all becomes much smoother!
Being able to keep things in a bag and bring >100ml is a total win but I expect it will be a 1yr training and learning process before it all settles down. Would be great if could keep jumpers belts and shoes on too…. or have a TSA Pre type program!
