And for the OP’s benefit, this is 355 days in advance, at midnight UK time (but 1.00 a.m. during BST) and that is a ‘guarantee’ for long haul flights. Not there is
no guarantee for F at all, though some routes can regularly have good availability e.g. NYC.
PS For SH (again IIRC) it is 2J4Y. And there are times in which BA releases more that those numbers of seats, so sometimes you can do a dummy booking and see no number it just says ‘seats available’, which could be any number over the guarantee.
