Plus according to the OP the flights were paid for MONTHS AGO, so there's no way credit card fraud can possibly happen as you have like one week from receiving your last statement to make any claims for funny transactions.
Nope, depending on where your card was issued and by whom, you could have anywhere between 30 to 90 days to contest the charges.
Card processors (Think: Moneris, Global Payments) themselves have even longer if they feel like a transaction
could be fraudulent, even if the cardholder isn't contesting. They regularly audit transactions, I guess in hopes of finding a problem with the merchant's handling and to deny the charge.
