"Crain’s Chicago Business reported that United Airlines is putting Ted on the “front lines” of a hotly contested battle for a new route to Mexico from Chicago, arguing that the Department of Transportation should approve its bid for the route based on the fact that it is a low-cost carrier and is good for competition. The piece noted that United is competing against Frontier Airlines and USA 3000 for the route."
Would that be Cancun the article is talking about? It seems to me that United lacks frequency to quite a few Mexican destinations. I'm also surprised that United isn't looking to restart service to GDL. ATA's flight out of MDW always seems full.
