I've been using my Alaska Airlines Visa card for a bunch of transactions over the last couple days. All of a sudden the card stops working.
Just says try another card. So I used another card for a while and then the same thing happens. I called AK Air credit card line and they said they couldn't help. I checked with Visa and they don't show it being denied.

Any ideas?

It is almost like if you use a card for two many transactions it gets freaked out.
