I would notify my cc company to watch for possible fraud. I too cannot see why a credit card number would appear on a voucher.
I don;t trust AA since the fraud in Aruba. People who used cc to book flights on AA returned home to find a mess of charges made in Aruba. If those people had notified their card company they would be using it in Aruba those charges would have passed muster. Result was found to be a booking agent for AA sold card numbers to people in Aruba and other places where flights were booked to. At that same time a certain restaurant copied card numbers for fraud use. That restaurant is no longer in business.
I do realize it could have been any airline.
I ran into trouble after booking a flight and obtaining Allianze travel insurance. That was found to be an agent at that company.
