Virgin Atlantic used OpenAI's Codex to ship its revamped mobile app on a fixed holiday travel deadline, achieving near-total unit test coverage and zero P1 defects. VP of Digital Engineering Neil Letchford reported that refactoring tasks that previously took two weeks now take 30 minutes to an hour. The airline also deploys ChatGPT Enterprise across HR and finance and uses OpenAI's realtime voice API for its voice-powered travel concierge.
