Confirm with your bank whether the charges in question have posted or are pending to your account. At the time of reservation a "pending charge" is placed on your account for the full amount. The bank/credit card company then puts a "hold" on that dollar amount, until the transaction either posts or is cleared. With a successful transaction, the charge will typically post to the account within 2 - 3 business days, at that time the money will be deducted from your account, and the "hold" will be released. At times the "pending hold" can show on your account after the charge has posted. Please allow time for the "pending hold" to return to your available credit. This is dependent on your banking institutions policies.
Please note: Your initial quote may not include seat charges, insurance or any additional services requested. These services are charged at the time they are selected and will increase the total cost of your trip. Posted charges may appear in multiple transactions which should total to the amount you were quoted.
