title: "Fernwick Air: rebook after a missed connection, tier off"
description: |
  Tier off. No model touches the intent: a rep reads the customer's message, rebooks them in the
  booking system and replies. Anyone can write to the contact centre, so the message is untrusted.
  Fernwick Air is fictional.
