It's not discontinued nor a dead link, it's missing, right?

Most likely reason why you don't see the MBNA Alaska Airines card listed is because your IP address is Quebec based.

People who live in a border town such as Hull, QC have crossed over to Ottawa, ON and with a new Ontario ISP connection they can then see the Alaska card listed at the GCR site.

This behavior started when MBNA changed it from first purchase to now requiring $1000 minimum spending.
