Things continue to get worse

Earlier on in this semester I commented about Delta Airlines filing bankruptcy soon after another airline filed to. Well things continue to get worse for the company of Delta Airlines. A recent CNN article states that Delta Airlines now faces liquidation. This means they are at risk of being disbanded into other airlines. Delta is at higher risk of liquidation than its sister company Northwest Airlines. This is due to the fact that it has nothing to fall back on like Northwest Airlines. Northwest can fallback to smaller flights located throughout the northwest. My question is whether things like this will continue to happen to Airline companies in America, and what will happen to the economy if Airlines start to be liquidated?
