Yes, "non-revenue" travel—commonly known as standby flying—is one of the most famous perks for airline employees. Pilots, flight attendants, and even ground staff typically receive unlimited or deeply discounted flights on their own airline. The catch is that they can only board if there are empty seats after all paying passengers have been accommodated; if the flight is full, the employee has to wait for the next one. Many airlines also provide "Buddy Passes" to give to friends or family, though these are often more expensive and have lower boarding priority. Additionally, most major carriers have "ZED" (Zonal Employee Discount) agreements, allowing employees to fly on partner airlines for a small fraction of the standard ticket price. While it requires flexibility and a "go-with-the-flow" attitude, this benefit allows airline staff to travel the world for almost nothing but the cost of airport taxes.
