So does AS provide beverage service on it's 737 flight? I'm going to say servicing a 737 vs. a Q400 on this route is a bit more of a challenge.
I've not been on an AS mainline flight SEA<-->PDX since 1980-something, but I'm always impressed how efficiently the QX FAs can complete a 74-person beverage service (including pouring a glass of wine or beer for a lot of pax) on that ~30-minute flight
