the airlines have to balance convenience and frequency with revenue and cost ... and they have determined that it's more profitable to use smaller aircraft on most if not all the flights in short-haul markets like SEA<->PDX/YVR/PSC ... that said, though, I've seen a handful of mainline jets on SEA<->PDX recently (both AS and DL)
