The PDX rampers are normally rockstar. The SEA rampers are excellent as well. I’ve had some of the best maintenance and tightest loading crews in the system at both those locations. I’ve been told they are borne in the fire of SEA arrival time into MEM driving the sort time. Makes sense, and with PDX serving basically the same flight time into MEM & providing shock absorption to relieve SEA freight, I’d think PDX is a tougher ramp. Just my observation over a few years.
But PDX (and SEA) have had domestic issues these past couple years. I’m not surprised it’s tough to staff both locations.
