I fly ex EU and ex US - BKK quite a lot.
If I can, I fly the fabulous QR J product. It helps me keep my BAEC gold with a nice lump of TPs and really is a great experience. I think BA's J product is poor and the BA9/10 CW experience is appalling but I think in Y, its OK, At least it's not an accursed 10 abreast 777 (yet!!)
