Today, the Justice Department announced the deal between United Airlines and Delta Air Lines to buy slots at Newark Liberty International Airport had fallen through.

United Airlines originally agreed to buy 24 federally regulated slots from Delta Air Lines, but the United States government sued to stop the sale, claiming that it would result in higher fares and fewer options for travelers.
Instead of moving forward with the deal, United Airlines abandoned the original plan.

Before the proposed deal, United Airlines already controlled 902 of around 1,200 slots at the Newark airport. To combat the deal, the Federal Aviation Administration announced last week that it would be lifting slot controls at Newark to promote competition.
