CNS, ABX, AVV, MEL and TSV were reportedly the routes doing well out of MCY. The remaining (non axed) routes out of MCY reportedly mediocre at best and the point to point non-base routes (e.g routes not touching the existing bases such as intra-Qld originating of WTB or CNS) have largely been dismal.
The five mentioned cities out of MCY could theoretically be served by 2 lines of flying by reducing the base to 1 aircraft overnighting out of MCY, whilst the second line of flying out of MCY could be formed with a early morning flight from MEL before said aircraft returns to MEL in the late evening (as the flights between MCY and MEL currently do). Perhaps the second line out of MCY could operate 4-5 days a week (on the days MEL-MCY operates).
