Step 1
Confirm which carriers, regions and status fields the API actually covers.
Step 2
Ask how often schedules refresh and what happens when upstream data is delayed.
Step 3

Test with flights you care about — not only the happy-path demo payload.
Step 5
Compare on APISeeker, then verify docs and playground behavior before committing.
