LAX-GDL-ANC will certainly be three man ops. It will be interesting to see if they try to use an SO or an LAX based FO for this as the 3rd man. Not many FOs left on the -400/-8 in LAX. Most were given / offered 777 courses.
It will also be interesting to see if the frequency will increase. Certainly that would be a sure sign that the route is successful.
