defintely give it a go. Its a lovely cabin.
But if you are looking for privacy, then its is not the same as BA F. The curtain issue behind the cabin and in front couple and with way the seats are laid out, does not give an exclusive feel. But the 8 seats a definite plus.
Ive only flown the intl route on the 773, so thats I am comparing. I have also done the old F config MIA LAX, and that was good as well, tho more seats tha BA F.
They both compare well to BA and is certaibly better than the 777 with BA.
Service wise and food - each to their own. Booze wise, BA better.
