Can't book award flight because all cards declined
I'm trying to book an award flight but all of my cards have been declined by Delta's system. A colleague couldn't book a paid fare last week because his card was declined.
Is there some secret to getting cards accepted on Delta? I've spoken to 2 agents today trying various cards and neither had any luck. One was my wife's using a totally different bank than mine. They are all non-US cards, 2 Visa (1 credit and 1 debit) and 1 MasterCard. The issues seems to be address related, as was my colleague's.
Banks are closed today so I can't get an exact reason why the cards were declined.
