BTS TranStats

Coverage, history and release timing vary by database; the Reporting Carrier On-Time Performance table is monthly, spans 1987-present and had data through August 2026 when checked. Large tables with millions of records can restrict all-period or all-geography selections, and the provider directs users needing complete multi-year extracts to support.
