On eurofleet at lhr we already have daily fight with pax as we cannot accom all the hand baggage we routinley fill wardrobes to the ceiling we throw 4/5 bags in the flight deck (unsecured) just to make on time departures.
IMHO ezy pax are very different to lhr biz men who carry a trolley and a laptop often these trolleys will only fit lenght ways ie. 2 take up an entire locker.
The baggage gagues !!!! what a joke haven't we seen all this before they become door stops and no ground staff enforce them. The bag should fit within the constraints of the whole cage no just dunk it in and out so it could be 6ft tall but only 24in wide and they let it on.
Sorry rant over
