A staff flight ticket, often referred to as a "non-rev" (non-revenue) or "standby" ticket, is a specialized travel benefit provided to airline employees, retirees, and sometimes their family members or "buddies." These tickets allow eligible individuals to travel at a fraction of the cost of a standard commercial fare—often paying only the government taxes and small administrative fees. However, the primary trade-off for this steep discount is that the traveler is on "standby," meaning they are only granted a seat if there are unsold spots available after all paying passengers have boarded. This makes staff travel highly unpredictable; an employee might wait at the gate for hours only to be left behind because a flight is full. In the industry, these are frequently categorized under codes like "ID90" (90% discount) or "ZED" (Zonal Employee Discount), and they require a high level of flexibility and "load checking" to use successfully.
