Have never been charged, though have been marginally (=<15kgs) over the limit on various airlines. On airlines I have no status, on each occasion I have notified the TA/ airline in advance and have received at least a 5kg "advance". Even when I was 34kg's on a 20kg limit, QF have said there is no reason to charge because they'd "budgeted for my excess" (kudos to QF amongst others on this matter) .odoherty said:Flew American this morning and saw a couple charged USD$100 for marginally overweight baggage. Pretty poor form imho.
Call in advance and even airlines can be accommodating.
