Total system includes scheduled service and fixed fee contract. System revenue passenger miles and system load
factor are not useful statistics as system available seat miles include both ASMs flown by fixed fee flying as well as
non-revenue producing repositioning flights used for operational needs. Fixed fee flying is better measured
through dollar contribution versus operational statistics
