For the best deals on Alaska Airlines, aim to fly on Tuesdays and Wednesdays, as these days typically offer the lowest fares. Avoid weekends and peak travel periods, which usually see higher prices. Flexibility with your travel dates can enhance your chances of finding cheaper flights. Additionally, booking at least 21 days in advance and keeping an eye on seasonal sales can lead to significant savings. Signing up for fare alerts and checking the airline's website regularly can also help you spot the best deals as they arise.
