Tips for booking cheap Alaska Airlines flights
Alaska domestic fares tend to be most competitive 3 to 6 weeks before travel. Hawaii and Mexico routes benefit from booking 6 to 10 weeks out during peak season.
Alaska Mileage Plan miles are earned on oneworld alliance partners and a wide range of hotel and car partners. The program offers some of the best sweet spots in the industry for redeeming miles on partner airlines including British Airways, Cathay Pacific, and Japan Airlines.
The Alaska Airlines Visa credit card gives the primary cardholder and up to six companions on the same reservation one free checked bag each — a useful saving on Hawaii and Mexico trips.
Alaska's Saver fare is the lowest bucket, with no seat selection, no changes, and no upgrades — but it's a good option for simple point-to-point travel if you're flexible on seating.
