Sorry I am typing faster than my thoughts.
Well, I setup a scedule plan for Vancoover to tampa but I have seen no evidence that my plane had carry any pax or even make the journey.
OK. Did you assign the schedule to one of your aircraft? If so, it should be flying. If you click on 'routes' (top blue bar of screen), then click on 'view routes - most profitable first' shou should see a list of all the routes you've created, including the loads and the profit.
If you go to routes-->scheduling you'll see your plane's schedules. That's also where you assign the a-check and b-check.
When I setup a flight plan for Vancoover to Denver I got a RED flag. but says I can still continue if I so wish.
I cant explain more as I still dont have a full understanding how the airline game works
Something like what I've attached to this post? Depends what plane you're using, and how many seats it has. In the box I've put up, it says my plane will be limited to 57 seats due to the range. Since I fly those planes with 50 seats, it's no problem for me to create the route.
