Hunting for extra grams of whatever you hold to charge you more
It is one of those cheap airlines that preys on passengers luggage, weighting even tiniest of itemes that the passenger holds, while passengers are waiting in line, in order to charge for even slightest difference from the 7kg permit. They ask you to put everything you have on the scale that is put in the middle of the line, and if you don't pass, you are directed to buy expensive extra luggage. No mercy! We were flying from Tokyo to Sapporo, this airline was the only one with such a sneaky luggage weighting policy.
