A couple of days ago I read the Easyjet website general note, rather than the Ts and Cs and it said any weight, but dims of 55 x 40 x 20 apply. Any weight surely is any weight? People randomly applying rules that don't match reality is a serious problem. Having said that, I've never had anyone from any carrier ever show interest in my bag size and weight, and that's for c. 30yrs of travel.
