Is this normal?: I booked an around the world classic award (Oneworld, economy) for myself and 2 kids back in December. I was charged $1498 in fees. I added some flights in January and was charged more fees ($629) - plus I used points to cover the Change Fees and International Service Fees. They have finally got around to sending me the eTicket by email and now they have charged my credit card for an additional $670.80. They have not said what this is for. Could it be because the Aussie dollar has dropped since I booked? Do they have the right to change the fees like this after it is booked and the charges been paid?
