This paper uncovers the effects on passengers from United Airlines’ 2014 de-hubbing of Cleveland Hopkins International Airport (CLE). Airline networks are often reorganized for efficiency; during the process, an airport may gain or lose hub operations, affecting passengers in different ways depending on the market environment. I take an empirical approach using difference-in-differences models to analyze 28 quarters of Bureau of Transportation Statistics data. I find that de-hubbing contributed to significant reductions in airfare per mile out of CLE. This is consistent with past cases of de-hubbing where low-cost carriers were present. However, quality measures, including the number of nonstop destinations served and on-time performance, were harmed.
