Flight search comparison, Atlas vs Comet
The author gave ChatGPT Atlas and Perplexity Comet the same nonstop SFO to NYC flight search for a wedding trip, with airline and airport preferences.
Atlas returned 11 round-trip combinations with times, airports and prices. Comet gave general statements and pointed to aggregator sites instead of pulling live data.
Overview
How it was set up
Same prompt given to both agents: nonstop SFO to NYC, April 24 to 26, 2026, United, JetBlue or Alaska, JFK or LGA preferred. Atlas ran in logged-out browser mode.
Worth knowing
Atlas first failed with a no-data error before switching to browser mode. Eleven options was slightly too many.
A prompt to start from
