Airline chatbots handle flight status, check-in, baggage tracking, rebooking, and disruption alerts for millions of travelers before an agent ever picks up a phone. That part is well covered by every page that already ranks for this term. What those pages skip is the harder question: who answers for the chatbot when its fare or refund answer is wrong. A British Columbia tribunal already settled that question for Air Canada, and the ruling should change how a VP of CX scopes any airline chatbot deployment. The risk was never the AI itself. The risk is a policy answer generated with no deterministic check behind it and no record of why the bot said what it said. ## What an Airline Chatbot Should Resolve, by Journey Stage An airline chatbot earns its budget line across three distinct moments, not one generic "customer service" use case. Judge it by journey stage, because the failure modes are different at each one. Journey StageUse CaseFailure Mode Without Guardrails Pre-TripFlight status, check-in, fare and fee questionsBot states a fare rule or refund policy that isn't current, with nothing stopping it Disruption DayRebooking, delay and cancellation alerts, partner-flight reroutingVolume spikes past agent capacity; the bot gives inconsistent rebooking answers to the same question Post-TripBaggage claims, refund requests, complaint routingHandoff carries no context, so the agent restarts the conversation and the liability exposure from the first answer is still live Finnair runs a generative AI assistant called Sisu on its [website and app](https://www.finnair.com/en/bluewings/world-of-finnair/meet-sisu--the-ai-assistant-that-actually-listens-4261942), supporting 15 languages. Singapore Airlines runs a branded assistant it calls Kris. Both are proof that airlines are comfortable putting a conversational layer in front of customers at scale. Neither answers the question this post is actually about: what happens the day one of those assistants gives a wrong answer on something that costs money. That's where [a buyer's guide to AI agents for customer service](https://www.voiceflow.com/blog/ai-agents-for-customer-service) earns its place in your evaluation. Most vendor demos show the happy path. Score the vendor on the unhappy path instead. ## Who Is Liable When the Chatbot Gets Policy Wrong In February 2024, a tribunal ruled on exactly this question. Air Canada's own website chatbot told a customer he could apply for a bereavement fare retroactively. He couldn't, under the airline's actual policy, and the airline refused the refund. Air Canada argued the chatbot was "a separate legal entity" responsible for its own words. The tribunal rejected that argument outright and held Air Canada liable for negligent misrepresentation, as reported by the [American Bar Association's Business Law Today](https://www.americanbar.org/groups/business_law/resources/business-law-today/2024-february/bc-tribunal-confirms-companies-remain-liable-information-provided-ai-chatbot/). That ruling isn't a quirky Canadian footnote. It's the default answer everywhere a chatbot states company policy: the company said it, full stop. A chatbot doesn't get to be a legal buffer between a wrong answer and the business that shipped it. Liability doesn't move because software wrote the sentence instead of a person. So the only lever a CX leader actually has is what the bot is allowed to assert in the first place. Everything downstream of that decision is damage control. ## Guardrails Beat Free Text for Fares and Refund Policy The fix isn't a better prompt. A model told to "be careful about bereavement fares" will still generate a wrong answer with full confidence, because nothing in a prompt stops free-form generation from inventing a plausible-sounding policy. The fix is architectural: answers about fares, refunds, and change fees should come from a grounded source and move through a defined path, not from the model guessing at what sounds right. That's the difference between a [workflow](https://www.voiceflow.com/docs/documentation/build/workflows), where every step runs in a defined order and a policy answer is retrieved rather than invented, and leaving the model to generate freely on a topic with legal weight. Put the fare-and-refund surface behind a workflow with a known answer source, and the chatbot stops being a liability generator on exactly the questions where Air Canada got burned. This is the one line item worth writing into an RFP: ask every vendor how their bot is structurally prevented from inventing policy, not how good their model is.

It needs a live connection to the reservation system to answer "where is my flight" correctly, a connection to the CRM or ticketing system to pick up a case where a human agent left off, and a connection to the contact center platform to route a call or chat without the customer repeating themselves. This is also where a compliance requirement belongs in the evaluation, not as an afterthought. If the chatbot handles payment details or personal information in transcripts, ask whether the platform can mask it before storage. Voiceflow's [PII redaction](https://www.voiceflow.com/docs/documentation/build/data/pii-redaction) is one example: a project-level setting that replaces more than 35 types of personal data with markers before production transcripts are saved, applied to live conversations rather than retroactively. Whatever platform you evaluate, that capability belongs on the same checklist as the integrations. None of this is about deflecting more contacts. It's about [resolving them correctly](https://www.voiceflow.com/blog/customer-service-automation) the first time, which is the actual cost lever, not ticket volume. ## Design the Handoff Before the Disruption Hits The handoff to a human agent is a risk control, not a fallback for when the bot gets stuck. Treat it that way in the design, or you'll regenerate the exact liability problem the chatbot was supposed to remove: an agent picking up with no context, repeating the same wrong policy answer because nobody told them what the bot already said. A clean handoff carries the full transcript plus whatever variables the team chooses, an AI summary, a case ID, the reason for escalation, logs the agent's own messages back into the record, and can return the conversation to the bot once the human part is resolved. Voiceflow's [live agent handoff step](https://www.voiceflow.com/docs/documentation/build/steps/handoff) works this way for chat and digital channels. For phone, the equivalent is a [call forward step](https://www.voiceflow.com/docs/documentation/build/steps/call-forward) that transfers a live call to a number or SIP address with caller ID intact, so the agent knows who they're talking to before they answer. Design this before a disruption day, not during one. Weather and mechanical delays don't spread evenly. When a hub shuts down, contact volume doesn't rise gradually, it spikes all at once, and the chatbot has to absorb that spike without the guardrails loosening. Voiceflow's own infrastructure is built to process up to 300,000 messages a minute, which is the kind of scale an airline actually needs on a bad weather day, not an average Tuesday. ## What to Measure to Prove the Risk Is Under Control Resolution rate and cost per contact are necessary numbers. They're not sufficient on their own, because neither one tells you whether the bot resolved the case correctly or just closed it. [Customer service metrics](https://www.voiceflow.com/blog/customer-service-metrics) that stop at volume and speed miss the dimension that actually created Air Canada's problem: accuracy on the answers that carry legal weight. Add a layer that scores the content of the conversation, not just its outcome. Voiceflow's [evaluations](https://www.voiceflow.com/docs/documentation/measure/evaluations) use a model to read the full transcript and score it against criteria your team defines, with three built in by default: customer satisfaction, deflection rate, and resolution outcome. Pair that with an [analytics dashboard](https://www.voiceflow.com/docs/documentation/measure/analytics) that tracks resolved conversations, latency, and cost alongside those evaluation results, filterable by environment, so you can see whether accuracy holds up specifically on disruption days, when volume is highest and the bot is under the most pressure. That's the evidence a VP should want in hand the week after the next disruption, not a quarter later when a complaint turns into a claim. Take three questions into your next team meeting. What's the guardrail stopping the chatbot from inventing a fare or refund answer, and can you point to it. What does the handoff actually pass to a human agent when it escalates. And what was the resolution rate, not just the contact volume, during the last disruption your airline handled. If nobody on your team can answer all three today, that's the gap to close before the next one hits. ## Frequently asked questions **What can an airline chatbot do?** It handles flight status, check-in, baggage tracking, rebooking, and disruption alerts across the pre-trip, disruption-day, and post-trip stages of a journey, each with different failure modes if there's no guardrail on policy answers. **Which airlines use chatbots today?** Finnair runs a generative AI assistant called Sisu on its website and app, supporting 15 languages, Singapore Airlines runs a branded assistant called Kris, and Air Canada's website chatbot handled fare questions before a 2024 tribunal ruling exposed its risk. **Who is liable when an airline chatbot gives wrong information?** The airline is. In Moffatt v. Air Canada, a BC tribunal rejected the argument that a chatbot is a separate legal entity and held Air Canada liable for negligent misrepresentation over a wrong fare answer. **How does an airline chatbot hand off to a human agent?** A clean handoff passes the full transcript plus chosen variables like an AI summary or case ID, logs the agent's replies back into the record, follows a fail path if the handoff can't start, and can return the conversation to the bot once resolved. **How do airlines handle disruption surges without guardrails breaking down?** They design for peak volume up front rather than average load, since contact spikes arrive all at once during a disruption and the fare or refund guardrails need to hold at that scale, not loosen under pressure.
