Straight up Y fare already. I was considering at $649; $999 - deal breaker for me. Oh well.

Looks like there are still a lot of a bunch of preferred seats open (specifically rows 22 through 24), unless pax bought tickets without selecting seats....

One seat (1B) in F and multiple seats back of the plane look to be blocked off.

Edit: interesting the same flight a day earlier (May 19) is also currently $999 in main cabin; $1,145 in C+; F is available at $1,425. 757 as the scheduled aircraft. Is there something going on in Boston around those days?
