Juan de Ayolas Airport (AYO)

Juan de Ayolas Airport (AYO) is a regional aviation facility located in the Misiones Department of southern Paraguay, serving the city of Ayolas and the nearby Yacyretá Hydroelectric Dam. The airport features a single 6,070-foot paved runway and a compact passenger terminal designed to handle domestic and cross-border general aviation traffic. Its proximity to the Paraná River makes it a strategic node for logistical flights associated with the massive hydroelectric project and for regional business travel.

The terminal building is a minimalist, single-story structure that integrates all administrative and passenger functions. While it is classified as a national airport, its infrastructure is primarily utility-focused, catering to private pilots, corporate charters, and government flights. Inside, travelers find basic waiting areas and essential facilities, though the environment is far more functional than a standard commercial hub. The airport is jointly managed by Paraguayan authorities and representatives from the Yacyretá Binational Entity.

Operational services at AYO are tailored for small to mid-sized aircraft. The airfield lacks a full air traffic control tower, so pilots operate under visual flight rules (VFR) and coordinate their movements via a common frequency. While there are no on-site retail shops or restaurants, the terminal provides a professional atmosphere for arriving and departing crews. The airport serves as a critical link for the remote Misiones region, especially when seasonal flooding impacts the local road network.

Security and passenger processing follow standard Paraguayan regional protocols. There are no large-scale TSA-style screening lines; instead, all identity verification and baggage checks are managed manually by local airfield staff and security personnel. Most travelers utilizing the airfield are part of pre-coordinated industrial or government missions, ensuring that the processing times are typically very fast. The airport is also a base for the Paraguayan Air Force during regional exercises.
