FFT1448 (Frontier Airlines) was operating from KHAF to KATL (Hartsfield Jackson Atlanta International Airport) on 2026-04-09. SkyMeter detected a diversion to Denver International Airport (KDEN) on runway 17R at 09:21 UTC. Peak cruise altitude FL338, turnaround area near Millard, US. Approach stability score: 63/100. Scores in this band occur on roughly 10-15% of approaches at this runway, with multiple gates outside the per-runway envelope. METAR at the time reported 8 kt wind, 8 kt crosswind component, 16,093 m visibility. Detection algorithm and known limitations: see SkyMeter methodology.

SkyMeter cross-referenced this flight against FAA-published TFRs that were active during its window and within its geographic bounding box. Overlap doesn't necessarily mean violation — the aircraft may have been outside the TFR’s precise polygon or flying under air-traffic-control coordination.

Automated analysis. Events shown on this page (such as go-around, unstable approach, or runway events) are heuristic classifications produced by algorithms from publicly broadcast ADS-B data. They are intended to surface flights of interest for further review — they are not findings of fact, and they do not determine pilot fault, regulatory compliance, or the cause of any occurrence. Coverage gaps and sensor noise can affect accuracy. Only the relevant civil aviation authority or accident investigation body can make official determinations.
