I know exactly how you feel BAPurser...
Just done a Lagos in First (14 Nigerian pax & their hand baggage each way), the Nigerians take full advantage of the new 18kg First Class allowance, trouble is there is nowhere to stow it all in A zone on the -400...I'm not even going to mention the Upper Deck. I don't know how LOS flights at LHR are dealt with on the ground, but at LGW ground staff have 3 times as many staff at the gate as a stateside -400 departure & we rarely get any probs down the back.
I'm all for giving premium pax the recognition & benefits they deserve, but lets look first at the logistics of putting new benefits such as increased hand luggage before putting them into practise.
