Public example

A tribunal held an airline liable for a refund policy its chatbot described

Air Canada's chatbot told a customer he could claim a bereavement fare after travelling. The real policy did not allow it. A Canadian tribunal ruled the airline was responsible for what its bot said.

AI answers change between runs and versions. This shows what was reported on that date and may since have changed.

What happened

01

The customer asked about a bereavement fare after a relative died.

02

The bot said he could claim it within 90 days of the ticket being issued.

03

The airline refused, because its policy did not allow claims after travel.

04

The tribunal rejected the argument that the bot was a separate entity and ordered compensation.

Why this is a design failure

The bot spoke with confidence about a policy that did not exist. People make money decisions on answers like this.

The fair alternative

Link the answer to the official policy text, and say clearly when it is not sure.

Do

Show confidence and link the official source.

Don’t

Don’t present a guess as fact.

Design guide for this case

If you're designing a support chatbot

Interface

Every answer about money, refunds or rules shows a link to the official policy page, right under the reply.

Words

In the bot's content guide: "For policy questions, quote the policy and link it. Never describe a rule from memory."

Flow

When the bot can't find the policy, it hands over to a person instead of guessing.

Metrics

Don't count "resolved by the bot" as success on its own. Track how many policy answers matched the official text.

Testing

Ask the bot 10 policy questions and compare each answer with the real policy, word by word.

Before launch

01

Does every policy answer link to its source?

02

Does the bot say when it isn't sure?

03

Is there a way to reach a person from any answer?
