# 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.

Result: 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.

## 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.

## Prompt

```text
Find nonstop flights from [origin airport] to [destination city, all airports], leaving [date] after [time], returning [date] in the evening. Preferred airlines: [airlines]. Preferred arrival airports: [airports]. Show all available combinations with times and prices.
```
