When would you obtain a fourth maintenance category?

Quite simple question, for the experienced players outthere…

I am having a succesful company, using 757’s, Superjet and Dash 8 400’s - but due to my very speciel airport, not many planes are very usable. (London City) I discovered a plane which can take off, and land at my airport with 284 seats! My problem is, that I will get a maintenance penalty, when I obtain my fourth maintenance category. When would you say that it’s “ok” to buy in a plane (or 20), which will penalize your economy?

Thanks in advance :slight_smile:

well, only you can tell. just do the math…

how much is your maintenance cost compared to your overall costs? I would guess something between 4 and 8%, depending on the a/c types and ages.

well, if you add another 15% to these 4-8%, it’s an increase of approx. 0,6-1,2% of your over total costs…

now it’s up to you to make that call if it’s worth it to you. keep in mind, that 0,6% out of a billion is a lot of money in absolute terms, but in relation…
