That was a very thorough and balanced review of BA First
T8191 - a highly informative read. ^
Quite a timely read as well for me as in the next few weeks I'll be using my GUF on an Avios booking for flights to HKG in August and was contemplating F on the outbound. It has definitely made me question whether to spend an extra 15k Avios for F in one direction or to use that to book a RFS before April 28 instead. I still need to get definite dates (although will still be flexible give or take a day or two), but it seems that there is only F availability on the 777 flight with no availability on the (seemingly superior) A380. I'll probably end up booking F on the outbound even if it's only a 777 (a plus of that is avoiding the flying dormitory), but a thought of doubt has definitely been instilled in my mind now...
After trying LPGS for the first time at the JFK CCR a few weeks ago, I could safely say that that would be a definite plus in flying F.
