Flight from Boise to Seattle

Verified travelerFlew with Alaska Airlines-Feb 2026

The seats are narrow. If you are large and expect to take up more space than your own seat, book two seats.

Verified travelerFlew with Alaska Airlines-Jun 2025

Seattle is not an easy airport to navigate. Going from RDM TO SEA is not a time saver. SEA Gates are far apart, it's crowded & not attractive. Flying into it is beautiful though. My advice - allow sufficient time (min 1 hour) for connecting flights. Love SFO for a layover if possible & flying out of LAX if international. Tucson airport was adorable & easy. Loved the artwork. PDX is a better alternative to SEA if possible; it has class.
