Coming back from Auckland on Saturdayit was being actively managed with people trying to board in the priority queue getting sent to the back of the normal queue. i was pretty surprised.
My favourite ever was Emirates F back from KL. Two jetbridges, one for F and one for everyone else and I was the only passenger in F. Queue lots of business class passengers getting turned away while they waited for me to turn up at my jetbridge. I suspect that will be the only time I'll ever have that privilege.
