OEP Frequently Asked Questions - OEP 35 Airports
OEP airports are commercial U.S. airports with significant activity. These airports serve major metropolitan areas and also serve as hubs for airline operations. More than 70 percent of passengers move through these airports. Delays at the OEP 35 airports have a ripple effect to other locations. For example, when delay trends at Miami International Airport for the years 2000-2005 were analyzed, it was found that delay increases were not correlated with increases in traffic at MIA or at Miami Center, nor were they related to Florida weather. Rather, they were highly correlated with delays at the other OEP 35 airports. Therefore, improvements at the most congested airports will have a positive impact on other airports as well.
The 35 OEP airports were compiled in 2000 based on lists from FAA and Congress, and a study that identified the most congested airports in the U.S. The OEP 35 airports do not change. Key FAA performance measures are based on data from this set of airports. These include: Airport Average Daily Capacity, On-Time Gate Arrivals, and On-Time Gate Departures. A stable baseline is needed for these measures to be meaningful.
