Are Thai Airways checking hand luggage weight at Heathrow?

The community consensus suggests that Thai Airways does not consistently check the weight of hand luggage at Heathrow. Several travelers reported that their hand luggage was not checked, while others indicated that it can depend on various factors such as the individual airline staff, flight capacity, and cabin crew mood. A few members mentioned experiences where carry-on luggage was weighed, but these seemed to be exceptions rather than the rule. Overall, it appears there's a degree of variability in how strict airlines are about hand luggage weight.
