Be careful what you wish for.
Some rumours have the 767s being replaced by the 7M8 out of YOW, at least some of the time. If that happens we’re going to be wishing for the 767s back. Even the 788 is a capacity upguage, and I don’t know if they can operate 888/889 and 838/839 with more capacity and still maintain acceptable loads. Hopefully these rumours are wrong...
