Pro Flight Search records official board updates for nonstop GRU to BYO flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

GRU to BYO questions
Is GRU–BYO running on time right now?
Mostly on schedule. The departure side at GRU is the weaker end, route health score 74/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from GRU to BYO?
Great-circle distance is 1,055 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 104–120 min gate-to-gate on this route.
How often does GRU–BYO fly?
LATAM Airlines runs the route with about 2 flights a week (wed, sat). Since one carrier owns the route, a single disruption tends to ripple through the day.
What does the route health score measure?
A blend of departure-side delay at GRU and arrival-side delay at BYO, computed from rolling delay windows (refreshed every 40 minutes) with a daily-rollup fallback. Current MVFR, IFR, or LIFR endpoint weather caps the score when flight rules can limit throughput. Higher is healthier: 100 means operations are clean at both ends.
