Philadelphia International Airport (PHL) is in the midst of preparing a Master Plan. The Master Plan includes strategies and time lines for airport improvements over a span of 20 years and also provides for thorough studies on the airport's efficiency and potential impact of any proposed new development at PHL.

The Master Plan is as much an assessment of PHL's current capacity as it is a projected outlook on the airport's future operational demand, expansion needs and potential.

Once the Master Plan's recommendations are approved by the FAA, the Airport Layout Plan (ALP) developed during the study will be implemented. The ALP is a graphic depiction of the airport that will guide the development of airfield, terminal and landside components.
