My mom is taking a direct flight from Hong Kong to Dallas, Texas (round-trip) through American Airlines. A relative purchased the air ticket for her in Hong Kong through the website of the airline (aa.com) using the relative's credit card.
Will my mom be asked to present the credit card used for the purchase at the check-in counter in Hong Kong International Airport and/or Dallas International Airport? Where can I look for the information?
I cannot find related details on the AA website.
