Hm, good to know, so JFK is not the last scheduled one.
I am in 1A, which I was really happy with, as 1A on the last flight is really cool

But might need to revise my plans now.
Edit: I see the 747 is scheduled on both JFK and PBM on the 3rd, which suggests that they will still have 2 Queens. I guess they will be around for a little while more.
