Return the United States Airline Industry to a semi-regulated state

In 1978 President Jimmy carter signed The Airline Deregulation Act in effect. Since then, many major airlines have gone out of business or merged with other carriers due to economic concerns, mainly Pan American World Airways (Which the US Government once called the "Chosen Instrument"), TWA-Trans World Airlines, and Eastern Air Lines. Air fares have fell, but that has come at a price. Due to high costs, airlines have started charging for everything other than the baseline ticket. Many mergers have happened, reducing competition. Limiting how much airlines can charge in additional fares, improving safety regulations, and restricting airline mergers only for when an airline will cease operations if it does not merge will improve the US Airline Industry drastically.
