Rouge has some 767s that aren't that old and there's a strong demand for 767 freighters at the moment and that will likely mean there will be support for them for a long time to come in the future. When 767s went to Route, AC kept/retired the oldest frames and sent the newest ones to Rouge. If the economy had not tanked with Covid, they probably would have lasted another 5-10 years in passenger service with high utilization, so that must be 20 years left as a freighter!
