Trying to book a flight from Hawaii to US Mainland via Krisflyer to take advantage of the 17.5K/pp. At the payment screen, it won't let me use either of my CCs to pay.
I'm getting this error message:
"Your credit/debit card is not valid for this fare. Please try again with another credit/debit card, or
select another flight and/or fare."
Neither my Chase United Explorer card or my CSR card work (which I've definitely used on past Krisflyer bookings). Any ideas?
