FAA Aircraft Dispatcher (ADX)Regulations (Part 121)Medium

A Part 121 domestic flight is scheduled for an aircraft with 120 passenger seats. Under 14 CFR 121.391, what is the minimum number of flight attendants required for this flight?

  1. A4 flight attendants
  2. B5 flight attendants
  3. C3 flight attendants
  4. D2 flight attendants
Show answer & explanation

Correct answer: C. 3 flight attendants

14 CFR 121.391 states that for an airplane with more than 100 passenger seats, at least one flight attendant must be provided for each unit (or part of a unit) of 50 passenger seats. For 120 seats, this means 120 / 50 = 2.4 units, which rounds up to 3 flight attendants.

Why the other options are wrong

  • A. Four flight attendants would be required for 151-200 seats.
  • B. Five flight attendants would be required for 201-250 seats.
  • D. Two flight attendants would only be sufficient for up to 100 seats.
