Air travel is a mode of transportation that involves traveling through the air using aircraft such as airplanes, helicopters, or private jets. It is one of the fastest and most efficient ways to cover long distances, connecting cities, countries, and continents. Air travel is facilitated by airlines that operate scheduled flights from airports, where passengers go through security checks and customs processes. Modern air travel offers various amenities, including in-flight entertainment, meals, and different seating classes (economy, business, and first class). It is widely used for both personal and business purposes, revolutionizing global connectivity and commerce.
