Delta<>Air France CC Presentation

I'm traveling with my mom to West Africa. I booked my ticket via the Delta website and it told me I'd have to present my credit card in order to be allowed on the flight. It helps avoid fraud.

A family member booked my moms ticket through Air France and I have no idea if AF told him the same thing or not. I asked but he doesn't seem to understand my question (English is his 3rd language). I'm just concerned because he booked using his own debit card and not my moms debit card. Our trip isn't for several months but I don't want to arrive to the airport day of and my mom cant board her flight because she cant present HIS debit card.

Hope I'm making sense. Does anyone know if Air France does this? I can't find any info online the way I can for Delta. I found 1 thing from 2016 but its on their Polish website. They're airline partners so I just want to double check.

It's been less than 24 hours and I'm just paranoid and considering cancelling and rebooking her flight either using my card (since we'll be together) or hers (though she doesnt have enough funds on a debit to buy 1.5K ticket nor does she have a CC). Any thoughts are appreciated.
