Anecdote != data, but my GPU cleared for tomorrow's UA90 (EWR-TLV) which has never happened before (I always get it on the return UA85, though). UA90 is one of the toughest upgrades in the system and a lot of those seats are paid BF. There's still open seats in BF. So either people are canceling trips due to present situation in Israel, or premium-class pax are spending their money elsewhere.
Just looked at the seat map (and I KNOW, that doesn't reflect actual load OK?) and the Y cabin which was almost completely filled the other day now has about 25 open seats. So maybe people are canceling or changing because of the crazy over there. If I could, I would've, but I gotta go because I like getting paid.
