Horizon doesn’t have a good commuter policy. Commuter clause only applies if you list with Alaska flights and offer no 4 nights stay at hotel like Compass does. There’s not much benefit for you to choose to commute for Horizon over Compass and Mesa. Buncha sitting during the reserve period without flying. You can pick up open flights at Mesa and make bank. Or fly with Compass even tho you may have to commute to LAX initially, which is only an hour away oppose to 2.5 hours to SEA or even more if it’s BOI or MFR.
