• 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 arrives late for boarding.
• C. A passenger who cancels a reservation.
• D. A passenger who is bumped from the flight.

Answer: (A)

A no-show is when a passenger has a confirmed reservation but does not use the space reserved and does not cancel. This label matters because the seat remains booked but unoccupied, which affects inventory management and may trigger no-show procedures or penalties after a certain point. It differs from arriving late for boarding, since a late arrival may still board if seats are available; the no-show status applies only when the space isn’t used at all. It also differs from canceling a reservation, where the passenger has chosen not to fly and the reservation is voided, and from being bumped, where the passenger is denied boarding for operational reasons but the flight still proceeds with other passengers.
