For your trip from Los Angeles to Seattle, the best time to buy your ticket is approximately 45 days prior to departure, when prices are at their lowest, around $181. Booking too early, more than 46 days out, can cost you up to $436, which is significantly higher. Additionally, prices remain fairly stable from 46 to 38 days out and may offer low fares even as late as 29 days in advance, but it’s advisable not to postpone your purchase beyond this point. After 29 days, fares become increasingly inconsistent, and by 21 days before departure, prices can surge rapidly, reaching highs of $464. If you find that you are less than 29 days away from your trip, it's crucial to book immediately to avoid steep price hikes, which could exceed 140% above the recommended 45-day booking period.
