I had a short wait at Tampa for a flight home after a work trip.  The gate I was waiting at did not have a lot of traffic nearby.  Indeed, judging by the total lack of lines at security, maybe none of the gates at Tampa have a lot of traffic!  The view from our gate was towards a cargo ramp and there were two 767 freighters loading up.  They both finished loading and taxied off while I was there.  One was in Amazon Prime colors but the other was unmarked.  However, a quick search tells me it is also a Prime jet but I guess they haven’t got around to painting it yet.
