Pro Flight Search records official board updates for nonstop BCN to IAH 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.

BCN to IAH questions
Is BCN–IAH running on time right now?
Significant delay risk. The departure side at BCN is the weaker end, route health score 50/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from BCN to IAH?
Great-circle distance is 8,425 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 625–752 min gate-to-gate on this route.
How often does BCN–IAH fly?
United Airlines runs the route with about 1 flight a week (mon). 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 BCN and arrival-side delay at IAH, 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.
