The F check-in followed by buggy ride through the J lounge was one of the iconic airline experiences. I'm glad I was able to experience it a number of times and am sorry to see the end of an era.

I suspect the lack of profitability had a lot to do with how F seats were routinely allocated to certain VVIP, often resulting in booting all other pax from the cabin. Probably easiest to stop that bleeding by just cutting the service.
