I got a call from this number. When I googled I found nothing.

This number is legit. I input an old procard number and it came back as invalid, so they called me. I told them I would call them back. Instead of calling this number, I went to Hawaiian Airlines directly and they confirmed that it was their number and that my procard declined.

This # is legit.  I called Hawaiian (not the # on the email).  This is a legitimate # for them.  I told them they need to google the # on the email and check it out.

Hawaiian airlines called my mobile phone from this number after I had made a reservation and used a credit card that was being declined. They had all the travel reservation info and reservation # so I feel pretty comfortable it was legit and gave them the new credit card info. (The card I used was canceled the day after I made the reservation for fraudulent charges)

Someone sends an email pretending to be from Hawaiian Airlines and tells you that your credit card was declined or something similar to that and tells you to call them.

IT IS SPAM! THEY WILL STEAL YOUR IDENTITY AND OTHER PERSONAL INFORMATION!!!!!!
