Convair CV-600. Operated for American Airlines, TTA Trans Texas Airways, Texas International Airlines and SMB Stage Lines. Scrapped.

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.
