Was informed that the 767-400 didn't have the range compared to the B767-300 and thats why there is only two operators that have them in their fleet. But the CO 767-200ER would have been one of the last passengers 200 series aircraft to come off the Boeing production line with CF6-80 fadecs engines and similar B777 interior and updated cockpit layout would be a nice addition to anyones fleet.
Air Mauritius used to have 2 x B767-200ER and they used them on the Mauritius direct Melbourne Australia flights on the longest ETOPs flights in world at that time, but now have been replaced by A340s
