After the credit card bought the plane ticket, the bank sent a pre-authorization message after the order was successful. Can I swipe my ID card directly when boarding the plane?

Credit card pre-authorization is to temporarily transfer money to the airline. If everything goes well, the transaction is successful. The money is transferred directly. If you refund the ticket, the money will be returned to your credit card.

For example, if you want to stay in a hotel, you must pay a deposit, 300 yuan (room rate for one night in 200 yuan). If you use a credit card, the hotel front desk will first draw 300 yuan from your credit card; This 300 yuan is pre-authorized. When you check out, the hotel will deduct the 200 yuan room rate from your credit card, and then return 65,438+000 yuan to your card. Therefore, the previous 300 yuan is only pre-authorized, and it will take effect after you confirm it.

Back to the air ticket, after you buy tickets online with your credit card, you have to change your boarding pass when you get on the plane (just like you have to go to the train ticket office to print paper tickets when you buy train tickets online). If you get your boarding pass, you will receive another short message confirming the success of the transaction.
