My flights top the ORS rating system for MCO to DTW with an 23 year old B757-200, yet i’m still not getting fully booked. Is this because I’m running my flights too frequently or because of the aircraft age?
the route is oversupplied. and since you are lacking the feeder network you can’t fill a bird as big as the 757.
Add some feeder flights to your hub (as mentioned above) OR get a nice IL partner at the other end.
