I have fleet of A320 and ATR42s (flynor)
I have extra ATR42s at the moment, coz they are cheap to buy so whenever C check is getting close, I re-base and switch the schedule so I always have an aircraft on the routes.
How ever A320s I do not have any backup. They are all on lease. I want your advice that If I lease an additional A320 for "backup" purpose, I do not have any routes to put A320 in at the moment. So it will simply be a spare aircraft with running cost, but no income.
How do I calculate if it is cheaper for me not to fly the route during C check, due to cost of extra aircraft, or is it better for me to lease an additional aircraft for C checks to save the loss of pax/revenue.
Also if this has any effect on Company or route image because A320 C check is 14 days. A route that is not flown for 14 days in a row in real life would have made very bad impression about the airline. B checks is bad enough (24 hours).
Is there an automatic setting to schedule another aircraft during B or C checks if you have a spare aircraft stationed at the base?
