They are extinct. As CDKing noted the subset that used to be the domestic 767-300 fleet has been reconfigured to a 2 class layout with BusinessFirst and as noted in other places in the thread are being used for international service.

There are 767-400 with barkaloungers which are in the process of being assigned to long-haul Hawaii flights from EWR, IAH, and possibly IAH. The plan is to install the old barkalounger PMUA P.S. seat in domestic configured 777 aircraft for Hawaii flights as well, although the conversion has yet to be started.

The 767-200 will be removed from the fleet, but are currently being used where needed on international and domestic flights.
