This is the first time I directly booked ticket on delta.com from LAX to MCO. The entire reservation process was very smooth. After exactly a week, my debit card was charged again. I called the bank and they said that they will initiate an investigation. I called up the airline too and they dont see additional charges on the same debit card besides the ticket that I have bought. I need to book another flight now but thinking against delta airlines if this is their usual practice. Wondering if anyone has faced any situation like this ? If so, please advice how to deal with it.
