Their merchant processor won't even accept Chase cards for in person payments.
In other cases, charges may require a manual VbV authorisation. In that case, you need to attempt the transaction and have it declined, call Chase VbV desk who will then authorise the amount and vendor, and then re-attempt the transaction. I have this happen maybe 50% of the time when I am booking airline tickets with Ethiopian Airlines and Kenya Airways as well as with Amazon's India site.
Thanks for the detailed information. For me, however, I'm not going to call Chase and ask permission to use my credit card all the time. I have other cards and they seem to work just fine.
