30 is definitely not too late; you have a long career ahead of you. The key is choosing a vocational program that treats you like a professional from day one. Look at the Professional Pilot Program at Pelican Flight Training. They take you from zero hours through Instrument, Commercial, and CFI. Unlike some university-attached
flight schools in the USA that drag on for 4 years, Pelican focuses purely on the flying skills and industry knowledge you need to get hired. They operate in busy airspace between Miami and Fort Lauderdale, so you gain serious experience. You could be teaching as an instructor in 12-18 months if you train full-time.
