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

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.
