An AvGeek (short for Aviation Geek) is a passionate enthusiast of anything and everything related to flight, aircraft, and the airline industry. For an AvGeek, the journey is often more important than the destination. They can identify a plane's make and model (e.g., distinguishing an Airbus A350-900 from a -1000) just by looking at the wingtips or the number of wheels on the landing gear. Common behaviors of an AvGeek include "plane spotting" at airport perimeter fences with high-powered cameras, tracking specific flight numbers on apps like FlightRadar24, and collecting "safety cards" or airline memorabilia. Many AvGeeks intentionally book "mileage runs" or multi-stop itineraries just to fly on a specific new aircraft type (like the Boeing 777X) or to experience a particular airline's business class product. They often speak a "secret language" of three-letter airport codes (like LHR, SIN, or DXB) and IATA airline codes. The community is highly active on social media under hashtags like #AvGeek, where they share photos of "wing views," engine start-up videos, and detailed reviews of airport lounges.
