This is awesome that the benefit has been codified to be permanently valid for any day of the week, but I am not terribly surprised because as I previously reported, I was able to apply a so-called free weekend night cert to book a weeknight stay at WA BKK before the pandemic. I simply called to whether my free weekend night cert, which would have expired if I did not use it at the time, could be applied for a Monday night stay. The agent on the phone at the time then said that she did see anything in the system restricting use of the cert only for weekend stays, so she successfully applied it for a Monday stay and I paid with points for a second night. I'd urged folks to try to see if they too could use the cert for weeknights and report, but then the pandemic hit and the cert's weekend restriction was lifted. Now it's been permanently lifted, but I suspect that the restriction was tacitly not enforced...
