My son and I were on that flight in November and we both loved it.
We were met at our gate and escorted (arriving from SZG) to a Senator lounge. Pretty unremarkable. We did not preorder our onboard dinner and were quite content with the offerings. I liked the caviar, but preferred that which was served on Asiana instead.
We received Rimowa amenity kits, making us both very happy.
Our seats were 1K and 2K. I have never been a fan of the center seats even when traveling with my husband. I prefer the privacy of the window seats and figure we can always have our meals together. I love my husband dearly, but I can stand not being with him every second. We sat in the forward mini lounge for a bit and I'm pretty certain we were the only two to use it.
The bathroom was huge with lovely Bulgari toiletries. Easy to change clothes.
I realize it's a hit or miss proposition with Thai, but I found this flight to be delightful. The attendants were lovely, always smiling, always proactive. I wouldn't hesitate to fly them again.
And of course, the meet, greet, and cart upon landing was wonderful.
