What best defines NO SHOW (N/S)?

• A. A passenger who has confirmed reservations for a flight but does not use the space reserved and does not cancel their reservation.
• B. A passenger who shows up late.
• C. A passenger who cancels a reservation.
• D. A passenger who upgrades their seat.

Answer: (A)

The main idea being tested is what “no show” means in airline terminology. A no show is a passenger who has a confirmed reservation for a flight but does not appear for the flight and does not cancel their reservation. Since the passenger didn’t cancel, the airline can’t count the seat as used, and the system may release that seat to others or re-sell it, depending on policy. This is different from a late arrival (the passenger still shows up, just later), a cancellation (the booking is canceled before travel), or an upgrade (which is unrelated to whether the passenger shows up).
