Hello Elpiloto,
There is no maximum age limit to become an Airline Transport Pilot (ATP) in the U.S. according to FAA regulations. You are only required to hold at least a commercial multi-engine certificate.
Please note that we do not offer ATP-CTP training at our facility. However, we partner with Simulator Center LLC for this program. You may reach out to them directly for inquiries: https://simulatorcentertraining.com/
