i put my MD-83 on a C-check for 14 days, so i shut down its route, for example: BUR-PHL-BUR days: 123457.
A few days later i switched part of this route to my other MD-83, only for days 57 and the slot fee was 0.
Now, the C-check is going to end in 3 days, i am rescheduling the BUR-PHL-BUR 123457 route to the freshly
maintained plane (of course, already removed the days 57 from the 2nd MD-83), but i had to pay a huge slot fee, like 200k$.
Were they expired in 10 days ? It makes me really upset...or is there a trick i'm not aware of ?
How is it possible to switch routes between planes without paying slots ? And then switch the routes back ?
Thanks and Kind Regards,
