Holiday Extras is rethinking what it can build with Codex
What happened
Holiday Extras used OpenAI's Codex to rebuild its main travel app, cutting development time from six months to two weeks and shifting from annual to weekly releases. CEO Matthew Pack led the AI-driven transformation, giving staff direct access to ChatGPT Enterprise and Codex to create software based on customer insights. VP of AI Innovation Liam Thompson worked with engineers to create reusable code packages, enabling simultaneous iOS and Android feature development. The rebuilt app boosted open‑to‑book conversion by 32.5% and allowed rapid fixes, such as turning a one‑star review into five stars after a quick update. The company also automated airport‑transfer chat handling into actionable tickets, further improving operations.
Why it matters
For ordinary travelers, the faster updates mean a more reliable, personalized booking experience and quicker resolution of issues. For businesses, it shows how AI tools can dramatically speed up product development and improve customer satisfaction.
Reality check
An automated, sceptical read of the sourceIncremental. The improvements are significant for Holiday Extras but represent an application of existing AI coding tools rather than a fundamentally new technology.
Is this a big deal?
