Thai also recently announced an all new business class is coming across the fleet - including lie flat in narrow bodies. Also bringing in Premium economy and new IFE.
Thai, for me, is a decent regional carrier (better than most) but a terrible long haul one. Hopefully this will finally allow them to properly compete.

It's also getting rid of first class except, for some reason, in just three B777's. I wonder why....(thinking occasional flights to and from a certain mountainous European location).
