Route System refers to which?

• A. The first flight of the day for each aircraft
• B. A large expanse of concrete similar to a road, used by aircraft for takeoff and landing
• C. The area in which an airline flies on a regularly scheduled basis
• D. Specific seats assigned to passengers at the time they check in prior to boarding

Answer: (C)

Route System describes the network of destinations an airline serves on a regular schedule. It defines where the airline flies and how often, including hub-and-spoke patterns, domestic and international coverage, and seasonal adjustments. This network shapes flight planning, crew routing, and what passengers can expect in terms destinations and frequency. It’s not about the first flight of the day, the physical runway or tarmac, or where passengers sit—the route system is about where and how the airline regularly operates its flights.
