Delta Air Lines opera parte de su flota con aeronaves de mayor edad, pero bajo programas de mantenimiento rigurosos que garantizan operaciones muy seguras. La antigüedad de un avión no determina por sí sola su seguridad: lo decisivo es un mantenimiento estricto y constante.
Vuelopedia is a work in progress: it currently holds about 30% of the information we expect to have by the third quarter of 2027. Although we use only official, highly reliable sources, some aircraft data and history may still contain errors or inaccuracies. We work hard to clear every anomaly from the records using specialized verification tools.
