BOEING 757-300 (TF-FIX)

ICE664 departing on 28L for Keflavik (BIKF/KEF). Arrived into PDX as ICE665 the day prior. My first time seeing the longer 757-300 from Icelandair at PDX and likely the very-first time the airline has actually sent one here! Didn't think the B753 had the necessary range to fly between KEF and PDX, unless the flights were operated with a restricted payload. Regardless, this was a rare sighting for PDX-spotters!
