China Airlines answers customers in dozens of languages with generative AI
China Airlines upgraded its online customer service to generative AI in May 2025, adding languages from German to Malay, and says it was the first Taiwanese carrier to put generative AI at the core of its online service. The upgrade follows a 2020 chatbot built on Microsoft's language understanding service. The airline has published no usage figures for either.

From keyword matching to generative answers

China Airlines' first chatbot went live in March 2020, as the pandemic pushed passengers online. It used Microsoft's LUIS language understanding service to interpret questions in traditional Chinese.
In May 2025 the airline upgraded to a generative AI platform, which it says gets past the limits of keyword matching to understand complex questions. It launched a redesigned website and an app supporting 12 languages on the same day.

The work behind the evidence
01 / Deployed
Answers in dozens of languages
The operational problem
An airline flying across Asia, Europe and North America takes questions in many languages, and a keyword chatbot struggles once a question departs from the wording it expects.
What the evidence reports
China Airlines announced on 22 May 2025 that its upgraded AI customer service runs on a generative AI platform using semantic analysis and logical reasoning. Chinese, English and Japanese were already supported; German, Spanish, Italian, Korean, Vietnamese, Thai, Indonesian and Malay were added, and the assistant also suggests destinations and itineraries. The airline described itself as the first Taiwanese carrier to make generative AI the core of its online customer service, CNA and Commercial Times reported.
Operational significance
A generative model widens what the assistant can understand, and also what it can get wrong. The upgrade is only as good as the grounding of its answers in the airline's own rules.
Evidence still needed
No technology partner, usage volume, resolution rate or escalation process has been published, and the "first" claim is the airline's own.
A source can verify an announcement without verifying its projected outcome.
02 / Deployed
A 2020 chatbot for a pandemic surge
The operational problem
In early 2020 travel disruption pushed large numbers of questions about flights, seats and fares onto the airline's phone lines and counters.
What the evidence reports
China Airlines launched its chatbot on its website and app in March 2020, ETtoday reported, using Microsoft's LUIS service to interpret casual wording and date expressions. It answered questions on check-in counters, gates, baggage carousels, membership, seat selection, special meals and fares, by voice or text, in traditional Chinese at launch.
Operational significance
The 2020 bot is the baseline for the 2025 upgrade: the same channels, a narrower language set and an older technique for understanding questions.
Evidence still needed
No usage or resolution figures were published, and the sources do not say whether the 2020 system was retired or absorbed into the 2025 service.
A source can verify an announcement without verifying its projected outcome.
The wider register
Other tracked activity
Other records are shown separately, including non-AI technology and programmes at different stages of deployment. A register entry does not establish a measured AI benefit.
No other publicly listed records.
Editorial assessment
China Airlines' documented AI is all in customer service, and it has moved through two generations of technology in five years.
The profile would gain most from the airline's own measures of the generative service: how many conversations it handles, in which languages, and how often it passes passengers to staff.
