Anyway, yesterday morning, about 3.5 hours before the flight, I logged in and checked again, and about 10 seats were suddenly available, mostly middles, but a few aisle/window, and one exit row aisle
I've noticed that J seats on late-afternoon JFK-LAX flights open up pretty frequently early in the morning -- in other words, seats assigned to people on J tix Europe-JFK-LAX who change/cancel/miss their XXX-JFK. That kind of thing probably happens ex-"HUB" with great regularity.
