However ACG is still in business instead of other competitors
Well, still in business.....its in business for the last 3-4 month, a startup should survive at least more than a year, so nothing special about this.
But a startup in cargo business usualy offers prices which hardly cover the costs of the flight, just to start the network. So even if you have 100t on that 744, it does not even mean that the flight is paid. Everything under 100t you are loosing money.
On US routes you dont make any profit at all.
