In the article, it is mentioned that the amenity kit will be given out to Royal Silk Class Passengers traveling on TG routes with flying time over 4 hours, except for flights operated with A320 aircraft.
As such, J class flights to China/India/Japan/Korea should have those kits. Any kind souls who have taken those routes recently can confirm? I'm planning two trips to PEK and TYO and will love to get my hands on those kits. Thank you!
