Legacy carrier: An airline that typically offers scheduled flights to major domestic and international routes (directly or through membership in an alliance) and serves numerous smaller cities, operates mainly through a “hub-and-spoke” network route system and has higher cost structures than low-cost carriers due to higher labor costs, flight crew and aircraft scheduling inefficiencies, concentration of operations in higher cost airports and multiple classes of services.

Load factor: RPMs divided by ASMs and expressed as a percentage.

Low-cost carrier: An airline that typically flies direct, point-to-point flights, often serves major markets through secondary, lower cost airports in the same regions as major population centers, provides a single class of service, thereby increasing the number of seats on each flight and avoiding the significant and incremental cost of offering premium-class services, and tends to operate fleets with only one or two aircraft families, in order to maximize the utilization of flight crews across the fleet, improve aircraft scheduling efficiency and flexibility and minimize inventory and aircraft maintenance costs.


NEO: New Engine Option.


On-time: Flights arriving within 15 minutes of the scheduled arrival time.


Passenger flight segments: The total number of passengers flown on all flight segments.


RASM: Passenger revenue divided by ASMs.
