the Oceanía–Terminal Aérea interstation, which is long, the track goes from the street level to the underground one, and when it was opened the track had a 4.9% slope. For the Terminal Aérea–Hangares interstation tunnel, slurry walls were built using the Milan method, and it is long. Near Terminal Aérea station, in Peñon de los Baños, workers found the remains of mammoths, bison, horses, camels, birds, and fishes, as well as a Teotihuacan settlement. Before the station was built, Mexico City International Airport was serviced by Aeropuerto station on Line 1 (the Pink line), located 15 blocks away. After Terminal Aérea metro station was built, people still got off Aeropuerto due to the confusing name and pictogram, an airliner silhouette. It was until 1997 that the station was renamed "Boulevard Puerto Aéreo" and the logo was replaced with a pictogram of a bridge with a dome below, in reference to local features. Incidents On 4 May 2015, an accident took place in Oceanía station when a train coming from Terminal Aérea metro station crashed another one parked at the end of the platforms. After the crash, the station was temporarily closed for repairs. Since 1981, subsidence increased the Oceanía–Terminal Aérea slope to at least 7% which contributed to the crash. To reduce the slope subsidence caused by rainfall, a tunnel was planned, but due to a lack of budget the project was canceled. Instead, an roof that cost 65 million pesos was built to prevent the tracks from getting wet and to avoid trains from sliding. From 1 to 16 March 2020, Terminal Aérea, Hangares, and Pantitlán stations were closed due to a leak of gasoline in a surface petrol station. Ridership According to the data provided by the authorities since the 2000s, commuters have averaged per year between 10,700 and 28,400 daily entrances in the last decade.

In the same year, the station was the 96th busiest of the system's 195 stations, and the line's 4th busiest.
