7kg or 9kg isn't a problem. What about 12kg? 15kg? 18kg? 23kg? 30kg?
Where do you draw the line? Gotta be somewhere. Well, it's been drawn at 7kg.
maybe they're travelling for an extended period of time and need more than what can be checked in.
There is no real limit on what one can check in. Practically, I think you are limited to 99 pieces of checked luggage due to the DCS (even then I have seen people with over 100 pieces sorted out by generating extra tags as unaccompanied in the DCS with a manual reconciliation - granted more likely to see this at an outstation using bingo sheets for AAA rather than at Dubai or any other stations with bar code/RFID readers). You can also consign anything above this amount via SkyCargo for transport on the same flight as you. There are many options available.
Still, I highly doubt that the number of passengers checking in 100 bags or more accounts for any more than a tiny minority of those with oversized/overweight cabin baggage.
