Demand dropping

[Dokhu]

Hello.

I've been checking the MDE-GRU-MDE route. After sending all my fleet several consecutive times I see that the demand decreases dramatically and I think this is bad thing because you can not use many aircraft for short routes because the demand drops more quickly and it is normal to have
 severeal daily flights as BOG-MEX in real life with ten daily flights. Besides a big aircraft is quite difficult to fill and if the demand drops they will be on the tarmac.

How much is the passenger limit per week?

Thank you.
