On-time rank ≠ volume rank
According to the U.S. DOT Bureau of Transportation Statistics, Saipan (SPN) ranks #1 of 369 airports on on-time rate at 94.8%, while Atlanta (ATL) ranks #1 on flight volume at 3,758,561 segments — and ExpressJet Airlines leads carriers on-time at 89.8% while Southwest Airlines carries the most volume at 7,582,834 segments. The tools below rank seasons and estimate delay risk from that same record.

Every tool here works from the same BTS airport record. At least 90.8% of the 382 tracked airports carry each independently-verifiable data layer, so a lookup rarely comes back empty. "Reliable volume" means ≥1,000 tracked segments; "Currently active" means 2024 data is on file; "Full 2020-2024 history" means both:
