* The name is slightly misspelled or different: Try searching for variations of the name, or checking for similar-sounding names in the area where you believe the school is located.
* It's a very small or newly established school: Smaller schools might not have a significant online presence.
* It's not a formally accredited flight school: Ensure you're looking at schools properly accredited by relevant aviation authorities.
To find a good pilot school, you should research schools in your area or region that are certified by the FAA (in the US) or the equivalent aviation authority in your country. Look for reviews, ratings, and check their instructor qualifications and fleet of aircraft.
