It's so far in the future, no idea what will happen, but i would not be betting on that middle seat being free. A and K will stay blocked as bassinet seats for the timebeing and will only open up near to depature if they haven't been used by those travelling with babies.

Personally I'd be booking a pair together and accepting that front row unlikely. Even when people are reclined I find the space in WTP acceptable.

Hope that helps
