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.
