Flights from Massachusetts to Seattle: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Massachusetts to Seattle 
Verified travelerFlew with Alaska AirlinesBOS-SEAOct 2024
Flying Alaska Airlines from Boston to Seattle was an example of getting exactly what you expect. A no-frills basic experience, but one where the important things were accomplished, timely departure, on-time arrival, no drama, no glitches, completely as anticipated. I paid a little extra for one offered perk (seat selection), and I'm glad I did because my early morning flight was full. Next time, I'll likely pre-order a snack, since they looked good, were served promptly, and are priced right.

It’s a good choice. Seattle airport is huge and confusing if you are changing planes. Have plenty of time to switch.
