I have bought 25kg baggage. When I self check in the first baggage, the machine show error. This machinr shows that the baggage weight is 5.6kg. after the staff help us with the machine, the first baggage successfully enters the machine. BUT when I check in the second baggage, which is 12.6kg, the machine shows that I have over weight. We call the staff again to verify the error. They told me that he first baggage check in is 13kg! The staff with unfriendly attitude said that you have two choice, one is to collect the baggage at arrival hall which will take one hour, other one is to buy extra 15kg luggage. This is very unreasonable solution! I am very unhappy with elthe attitude of the staff and the solution she provides to me.
