I left an item onboard when I disembarked, and didn't discover it until I was away from the airport. I filed a case with both Qatar Airways and SeaTac. SeaTac actually has a staffed phone line for lost & found; the fellow told me he would expect the item to possibly turn up at the "Qatar Airways baggage office on the mezzanine level".

Is there in fact such an office at SeaTac, and does anyone have any experience visiting it? I can't even determine what hours they'd be open.

Any info would be welcome.
