Count yourself Lucky!
I can show you people whom have been paid properly by Avionco, then the bottom falls out. There are other people that were cheated starting day one. Then others sit at home with no pay for weeks and months, waiting for Avionco to call any minute. Then a few others have a good go at it.
One thing is for sure, Avionco is not dependable, nor is it predictable.
It is good to hear that you are happy with them. But careful.
