How to become an airline pilot
The full path from zero hours to an airline flight deck — ratings, the hour-building years, and the regional-to-major ladder.
Becoming an airline pilot is a multi-year project, not a course. The typical path in the United States:
1. Private Pilot certificate (PPL) — learn to fly and solo cross-country. 2. Instrument Rating — fly in cloud and the IFR system. 3. Commercial Pilot certificate — get paid to fly; requires 250 hours. 4. Multi-engine rating and usually a CFI/CFII/MEI so you can instruct. 5. Build to ~1,500 hours for the Airline Transport Pilot (ATP) certificate — the legal minimum to fly for a U.S. airline (lower "restricted ATP" minimums of 1,000–1,250 hours apply to military and approved university programs). 6. ATP-CTP course, the ATP checkride, then a regional airline new-hire class and a type rating on their aircraft. 7. Fly the regionals, build turbine PIC time and seniority, then upgrade to captain and eventually move to a major airline.
The hour-building years (steps 4–5) are where most of the time and cost go; flight instructing is the most common way to log them while getting paid. Outside the U.S., many pilots use integrated/ab-initio programs and a frozen ATPL with far lower hour requirements but a structured airline cadet pathway.
There's no single route — the constants are the certificates, the hours, the medical, and persistence. See the related guides on hour-building, the regional-to-major ladder, and what it costs.
