I swear I'll never get in one now. Not as a passenger, nor as a pilot.
Not likely you'll get the chance to. There are only a few airframes left in passenger config, KLM and Finnair, and possibly a combi or two with Martinair, as far as I know.
All the rest belong to the freight community, FedEx and UPS mostly, with a scattering of various cargo haulers elsewhere in the world.
(Certain times of the day in Anchorage, you could swear every last one of them was present and accounted for on the tarmac at the same time, really impressive to see.)
