Their Dreamliners are quite nice - only their A320 was old and dirty. Much like US planes.
I'm a bit of a fan now actually!
The best part however is that I believe all my flights were credited to BA, even though I got the courtesy upgrades (believe, because no miles have been credited yet, neither to LA nor BA - but my BAEC# was on the boarding pass and I was upgraded).

After returning from my first trip to Latin America, I think the key thing is that people just don't speak English.
As soon as you can make yourself understood (either because you find the unicorn that does speak English - or somebody else can translate for you), the service was actually always quite good.
