As an EasyJet cabin crew, I can confirm you that the unlimited weight restriction policy is dreadful, specially in wintertime when passengers take off their coats and stow them in the compartments...Huge delays, a great deal of bags being offloaded to the hold which create a lot of tension b/ pax & crew.
I refuse to lift pax luggage, i'm not covered by the company's insurance...Yet, I sometimes have to do it if the passenger is frail, disabled, old or simply dwarfy...
