Alaska Airlines announced the launch of Flight Pass this week, a subscription service with two tiers to be redeemed for 6, 12 or 24 nonstop trips a year “to eligible destinations” in the Western U.S.

Flight Pass subscribers can choose between two annual plans: the “Flight Pass” starting at $49 per month or “Flight Pass Pro” starting at $199.

Credits under the Flight Pass system can be redeemed for travel on nonstop Alaska Airlines flights within California, and between California and Nevada or Arizona.
