I´m in MT2, but from what you explain, I would say that your variable or fixed costs are too high. What aircraft are you flying?
There are several good strategies currently:
1. Get 1 or 2 OK long or medium haul jets and fly them on routes with enough C demand, that will bring cash fast, but its a high risk approach. If the routes are not perfect you will go bust in no time.
2. Get 2-3 jets not older than 15 years and fly on medium haul routes with enough C demand, that will also shed cash, this is the medium risk approach. But it will take more time to mess with the big boys.
3. Get 4-5 props not older than 15 years, and fly tons of short routes, multiple times a day. Try to get props where you can cram in some C seats and fly on routes where there is some demand for them. This approach has lower risk, but those planes will not be cash cows. You need loads of them to get rich.
4. Get 5-10 smaller (20-40 seater) props, not older than 10 years and fly even more routes. This is the lowest risk approach, but also the slowest.
Common in all approaches is that try to squeeze out as much routes of your planes as possible, planes sitting on the tarmac are just making losses! You also need to invest somewhat in marketing, but how much depends on your approach.
I hope I could help.
