Thanks for all the tips - I have booked into Austin.
Wierdly BA auto allocated my seats - 30F which is the aisle middle seat and 30D on the other side coming back.
I didn't select the seat - and the entire row which is the exit front aisle at the start of WT on the 787-9 is empty
Is that normal? I have never seen an auto allocated seat on booking before check in?
Also where would be the best place to sit in WT as a Gold on the 789?
