"Researchers from Dartmouth and Carnegie Mellon University have developed a new model for airport flight scheduling that promises to manage air traffic congestion without systematically favoring certain airlines over others," writes The University Network.

"At the busiest airports, the combination of low capacity and heavy air traffic is a major cause of delays in the U.S., costing over $30 billion annually, according to the study. As a result, there is currently a significant effort being undertaken to review scheduling guidelines and research more efficient models. ...

..."'Previous studies have focused exclusively on the overall benefits to the system as a whole, including those to all airlines and all passengers,' said Vikrant Vaze, assistant professor of engineering at Dartmouth and co-author of the study. 'However, that is not enough, especially when there is a risk of distributing the benefits unequally. If equity is not accounted for, then all benefits might be enjoyed by a few airlines and passengers while others might gain nothing.'"
