Any idea if BA will install 1 or 2 lavs on the new 8F 77Ws? On the 789 only having 1 lav is a big problem (both in terms of waiting time and often cleanliness) with 8 passengers + cabin crew + flight crew. I'm not aware of any other airline that only has one forward lavatory for a similar first class cabin. For example AF and SQ with 4F on the 77W has 2 lavs and so does CX with 6F.
