Juan Serrato came from an aviation family, and was immersed in flying from an early age. His father was a Vietnam era helicopter pilot, and took him flying often. Juan attended a school as a teenager where aviation was part of the academic curriculum, and earned his Private Pilot certificate.

After high school Juan attended A&P school, and then was hired servicing airplanes. He then entered an ab-initio program with Mesa Airlines, barely making the cutoff because he had 148 hours and the limit was 150 hours. While attending the program, he worked as a mechanic on aircraft.

He became a first officer on the Beech 1900 with Mesa as a US Air Express copilot. He flew as many as 13 legs per day. He flew the 1900 for a little over a year, then became a first officer in the RJ (regional jet). He flew the RJ for two years, then became an EMB 145 captain, flying his first trip on September 11, 2001. He was inflight when all aircraft were ordered to land immediately due to the national emergency. He landed at Raleigh, NC. He was stuck there for three days, until his girlfriend drove down to pick him up.

At Mesa, he became an accident investigator, on scene for a fatal accident investigation for the powerplant division. He also became a simulator instructor and line check airman.

After nine years at Mesa, he was hired by Gemini Air Cargo on the MD-11, flying all over the world. After about a year, the airline went out of business, and Juan was hired by Southern Air on the B747 as a first officer, flying freighters. He flew a lot of trips out of Ethiopia on a 20-on, 10-off schedule. After two years, he was furloughed as a pilot, but worked in their headquarters on documentation.

After five years with Southern, he was hired by Atlas Air, flying several versions of the 747, including the LCF (large cargo freighter). He was at Atlas for four years, then was hired by a legacy carrier, where he works now as a flight instructor on the B737.
