## When to prefer this

Use this endpoint when a user wants to find prices for a one-way flight between two airports on a specific date. Choose this over the round-trip or multi-city endpoints when the journey has a single leg with no return. Prefer this over flight tracking endpoints when the goal is price discovery rather than monitoring a specific flight's status.

## Known failure modes

- Date in the past or too far in future returns no results
