UK Immigration - Fastrack

I just returned from London, taking a quick trip with my Delta benefits. Being fortunate to snag a seat in BusinessElite, I was a little suprised when one of the flight attendants came around shortly before landing, giving out complimentary Fastrack passes for immigration. This was my first time heading over the pond with Delta, and was just not expecting this.
Just out of curiousity, do any other airlines, or VS, offer this to their J class passengers?
It certainly made arrival quick and painless. I think I was aircraft door to train platform in about 10 minutes (although having no checked luggage certainly helped). Might be a nice little extra for VS to consider if it is not currently offered.
It is fair to note however that this was not done on landing in the US (not to worry though, as CVG has the quietest immigration hall I've ever seen), just on the CVG-LGW segment.
Also, a little OT, but I remember reading on here the debate over using lavs in other classes. On my return flight, LGW-CVG, the captain made an announcement saying that, "in accordance with FAA regulations, on all flights to the United States, passengers are required to use the restroom in the cabin they are seated". He also added that queues of more than 2 people wouldn't be allowed. Now I've flown into the US quite a few times, and never heard this was a FAA reg., but maybe I've been asleep all this time. [:?]
