Is it cheaper to buy a plane ticket from San Jose Intl. Airport to Seattle - Tacoma Intl. Airport (SEA) last minute?
Being spontaneous is a fabulous way to travel, but it isn’t necessarily the smartest method to find a cheap plane ticket. Think about booking your Norman Y. Mineta San Jose Intl.

Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. We recommend saving that spontaneity for when you’re exploring SEA!
