Surprised to see BA actively checking all cabin bags fitted the cage at the gate last week at LGW although it did look like some big bags got through. Same problem with inappropriate small bags in the overheads, and there is no legroom excuse in Club as there is space under the centre seat. BA don't help however, as all of the lockers above row 1, and into row 2, appeared to be full of galley equipment, as well as the usual demo kit - so the very seats that have to stow their baggage overhead had no space to do so.
