Seasonal Non-stop Service from San Diego to Zihuatanejo

For those that don’t know, the Alaska Visa card ($99 annually) comes with a $99 companion fare. With taxes the companion fare is $121. Counting the cost of having the card, the companion ticket would cost $200. So even though the flight from ORD looks pricey, if the second person pays $200, it becomes almost reasonable. If you pay with the card, you and anyone else flying with you gets a free checked bag.

Is there an annual limit on the number $99 companion fares?
