I had a fraudulent DL charge and credit on my credit card last month for a same-day domestic flight. Same with a SW charge not credited back. The crook took a same day purchase and flew on SW. Surprisingly, DL gave me the passenger’s name. Nothing else on my statement was fraudulent. I got a new card number. DL probably asked for the card (SW didn’t) and that’s why it was credited back. I gave VISA all the info and they didn’t care. Just said they’d write it off. Very strange.
