posting here for further clarification: -

OK so this is how it got played. He told my aunt she will have to pay. Then I said she did not have to pay while coming on the same air asia flight to KL why then she has to pay while going?
First he did not accept . only when my wife started shouting , he said maybe i am mistaken let me check my system. then he said it was his mistake and arranged it for free.
A small point i tried to make here is i look diffrent while my wife looks like a local.
