We booked two international flight air tickets but have to cancell and paid 2x$150 = $300 cancelled fee on top of the airfare. About three months after, we tried to rebook our flight with airfare credit, but the prices customer service quoted was more than double of the price we saw on their own website.
By the way, it took more than 2 hours to reach the right department and before they solved our new price issue, the phone got hang up.
Money loss: $2,558
