Pro Flight Search records official board updates for nonstop LIS to ORD 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.
Mostly on schedule. The departure side at LIS is the weaker end, route health score 81/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from LIS to ORD?
Great-circle distance is 6,435 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 484–582 min gate-to-gate on this route.
How often does LIS–ORD fly?
TAP Air Portugal runs the route with about 5 flights a week (sun, wed, thu, fri, 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 LIS and arrival-side delay at ORD, 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.
