Why can people not purchase tickets for Halloween horror nights? The site had declined credit cards from both Chase and bank of America. I called both banks and they said there was no issue on their end.

That must be something with their site or payment system. Also I have sometime experienced that informing credit card company about travel plans make them aware of area charge is being made. Hope this helps. Or you should call universal.

I would believe that it has to do with what the situation that we're having about covid, and delta. My thoughts, they're waiting to know what's going to happen. Remember LA county is always at a worse risk than the rest of the counties in California.

Let your bank know. This maybe a block from your bank.
