Awful service. We paid online for luggage 4 cases weighing 25, 25, 20 and 15 kg and when we checked in they were all under. The agent said we had to pay another 4000 Yen as we had not paid for extra. We explained that we had and she said she was unable to check us in so sent us to another agent. He was extremely aggressive and kept shouting "You pay, too much luggage" My husband explained the cases were all under weight and he said no you have too much. We asked if he could confirm the total weight but he refused. He then shouted "card declined, you pay now" We had not received anything to say the card has been declined. In the end he said we had to re-queue to check in or pay. Our 3 girls aged (7,9 and 11) were starting to get worried and it was getting late so we just paid it. I saw at least another 2 customers in same position arguing they had paid and then being charged again. Never again.
