It wouldn't matter how many they stuffed into containers, they still couldn't carry enough to pay the cost of the fuel they burn. If their management would have the nerve to raise the cost of a ticket, so that they could actually cover their expenses (crew, fuel, leases, jetways, etc, etc), then perhaps they could operate in the black. Until then, they are doomed. It's too bad, seeing as the U.S. commercial aviation industry was so strong just a short number of years ago.
