I asked CX this (again) a few months ago because BA also have a generous 3 x 32kg (+ 1 x32kg, if you're DM / OWE) on the LHR route

Reply was that they have no plans to change - which is what they've been saying for the past few years when I've asked.

I voted with my feet and flew with BA...CW isnt great but I can sleep reasonably well and the food is better
