I have make a minor mistake when booking for my daughter ticket. One of the character was misspelt and this lesson cost me $70. I have bought from Cathay Pacific agent, Zuji. Cathay Pacific was unable to do the changes within one working day even though Zuji had informed them.
At Changi Airport Terminal 4, I can actually change it for free. The inconvenience is I cannot do auto check in but need the staff to endorse on the ticket for the spelling mistake.
But anywhere, I have pay for it and therefore I expect the airline to do the name correction for me before I fly out of HongKong.
