it really isnt fair when someone turns up with nothing but a large briefcase, only to find no locker space as many others have oversize luggage or more bags than permitted.
I agree wholeheartedly!
The only trouble is, my own airline, British Airways, has had such horrendous problems with missing baggage that many passengers are understandably reluctant to let their bag go in the hold.
(Not all the fault of BA I hasten to add - a lot of this has to do with the ancient systems at Heathrow never designed to cope with the number of bags it is having to deal with!)
