Just got hit with the bullshit 'computer says no' $100USD charge on checkin at JAL in Bangkok travelling business class for total bag dimensions over 203cm with our DB (total length is actually 203cm). All the check in staff are just Thai contract, they were fine. It was the Japanese station manager who pulled out the tape measure. Tried to argue and get reasoning on the charge from him but all he would do is smile and bow. Have flown TG, CX, IB, QR, QF, AB, UA, AA all around the world with the DB and never had to pay as long as within weight allowance and never come across the total dimension charge. Pretty ridiculous really, but this is Japan hey. Won't be flying JL again. Luckily flying TG home.
