Am flying WT with my wife in 3 days, and finally made it silver on the inbound flight (in WT+)...so can finally pre-assign seats.

We are flying 3-class 777, and would obviously prefer the 15A/B or 15J/K if possible. The bassinet seats were greyed out until today, but have now appeared. However, when I click on either my wife's or my 'icon' to change seat, the bassinet position greys out. The do appear available (i.e not greyed out) when I don't click on either of our icons. It is less than 72 hours to our flight, so I presume that these seats should now be available, or am I wrong? What is going on?

thanks,

tb
