If you are on BA16 all the way to London then it's 24 hours (in essence) in one seat, so maybe that changes things? Would you be very disappointed with a central seat? On the other hand it's CS on that service so there is a high proportion of window seats and even if a seat isn't available at 7 days, there are often a lot of changes even after online check-in. If you are switching in SIN to the A380 then I think that diminishes the case, since you have a second seat selection go. Also the flight is in darkness for much of the time too. If you do pay for seating you can select other seats, there may be an additional amount to pay (or not) since it's dynamic pricing. The other option is to check seats regularly and buy only if forced, that is to say if the window seat options start to shrivel up.
