Insights shared by verified travelers who flew the route from Pennsylvania to Seattle 
Verified travelerFlew with Alaska AirlinesPIT-SEAOct 2024
Early Wednesday mornings must be the prime time to board because there was no time to stash my watch, etc. into my bag before security since there was almost NO line. Another bonus for morning people.
Verified travelerFlew with Alaska AirlinesPHL-SEAApr 2024
No US airlines have any easy boarding, comfortable planes, decent food offerings, ambiance, etc like they used to. Suggestions: take off baggage fees, start serving real food offerings ( not a snack item), treat all people on board as paying customers instead of just 1st class or premier seating. In other words, all US airlines need to step up their game!
