You think that even for the weekend before Thanksgiving? IMO, that changes things.
Of course, I'm one that will start stalking flights 11+ months out (yes, they officially come out 330 days early, but I'll look at similar times for the previous year if I can).
OP, if the price hasn't come down yet, just keep watching. If they don't come down, what are you going to do? If you won't fly and just drive, you can watch until the day of. If you'll just suck it up and purchase, book when you're comfortable. JB has $0 change fees if you do the change online, so still keep watching after you book.
