Well absolutely no entry issues on my AA flight from JFK-MIA.
I was preparing for a battle, and fair play to TSA for letting me through with my lance, but there was no dispute.
The BA desk agent waived me straight in, and there are now 2 passengers in here (including me!).
I was fortunate enough to have a long chat with one of the BA SS team (the lovely cardigan wearer who has now been forced into BA uniform - not putting her name).
She alluded to a few future changes coming, mostly to make the lounge more comfortable and also to improve the WiFi and phone reception which is terrible unless you sit to the right of the bar (that's where there is the best signal).
It's a very quiet space right now, and the breakfast menu is perfectly fine.
As for the space? It's big, airy, has plug sockets galore, and it's a sort of modern interpretation on the CCR which was a bit 'Grandma's house'.
