Predicting the past with old cookies

I just grabbed a handful of alphabet cookies to see what’s in store for me, and the letters were:

F L Y H T

So not only are the cookies out of date, they can’t spell.
I guess they have been sitting on my desk awhile.

There’s only a few left in the bag now. The last letters are:

B A ? K (the third one was just a fragment of a cookie)

so the whole thing was:

F L Y H T B A K

oh, “flight back”, well done cookies… you sucessfully predicted something that happened TWO DAYS AGO! I need some fresh cookies. Especially since this bag’s empty now.
