Me too... but on the 773 I have opted for 7A in one direction.. and 1A in the other... (I like portside window seats obviously)
The smaller cabin on both those flights is pretty full already (according only to the seat map) and in any case seems sandwiched between toilets and Y+ bassinet rows....
We'll see eh? I'm sure any "better" seats will become known fairly promptly....
.....around HERE at least!!!
