I left my Kindle in the seat pocket on my ATL-PVD Flight back in December. I unpacked the next morning and realized it was missing. 10 minutes later, I received a call from Chris the redcoat at PVD asking me if I left something on the plane. I told him my Kindle. They held it for me and I picked it up over the weekend.

I consider myself very lucky. I also think sticking a return address label (name/street address) in the cover of my Kindle helped expedite the return of my left item.
