Altoona Blair County Airport — Altoona, United States

In the ridge-and-valley terrain of central Pennsylvania, Altoona Blair County Airport carries the code AOO and sits roughly midway between Pittsburgh and Harrisburg. The field's elevation of 1,503 feet and its two-runway layout give pilots options depending on wind direction across the hilly Allegheny terrain. Blair County owns and maintains the airport, which functions as the primary air access point for Altoona and the surrounding communities. General aviation makes up most of the activity recorded at AOO, supplemented by limited scheduled passenger service typical of small Pennsylvania airports serving mid-sized cities away from major interstate hubs. That two-runway setup remains modest but steady, matching Altoona's size and the pace of traffic passing through the region.
