I can imagine this causing an absolute uproar at check-in.
We are usually under our 20 kg limit wherever we happen to be travelling home from but we do have some bits in our hand luggage.
Coming home from Cancun last month, they weighed both our hand and hold luggage together (no idea why, other check-in desks didn't!) and the total was 41.2kg.
The chap said 'Perfect'.
Thomson's new style ticket booklet is very clear about baggage allowance, they say in addition to the allowance shown on tickets they allow a further 5kg for hand luggage.
When we go in February, I'm going to try to make sure I take some sort of documentation relevant to my carrier that makes hand and hold luggage allowances clear.
I'm all for charging excess if people really ARE over their limit, but I'm certainly not going to line the pockets of anybody working at Dabolim airport.
