Airlines say a delayed flight can claw time back. We paired the same flight's actual departure and arrival clocks to check, then split the answer by how long the sector was scheduled to take.
Pro Flight Search paired board history · 2026-09-11 21:07 UTC
Among 1,005,796 paired flights that left 15 to 360 minutes late, the median flight reached its destination 29 minutes closer to schedule. This is gate-to-gate recovery and includes taxi time, routing, and timetable padding as well as time in the air.
What the paired sample shows
The room to recover
Longer flights make up more minutes
Scheduled gate-to-gate length is the cleanest way to test the airline line on its own terms. Each row uses flights that actually left at least 15 minutes late.
Find the closest cohort
How much do similar flights usually recover?
Enter the departure delay and scheduled gate-to-gate time. The result uses the exact sector × delay cell when it has at least 100 paired flights, then falls back to the broader delay cohort.
This is a descriptive cohort rather than a prediction for a specific flight. Weather, congestion, taxi time, routing, aircraft type, and timetable padding all affect the outcome.
How late it started
An hour late is a different problem from 20 minutes late
Recovery minutes and the chance of reaching the destination within 15 minutes of schedule, grouped by the actual departure delay.
| Actual departure delay | Median recovered | Recovered 5+ min | Arrived within 15 | Paired flights |
|---|---|---|---|---|
| 15 to 29 min late | 28 min | 92.9% | 92.1% | 482,023 |
| 30 to 59 min late | 29 min | 92.3% | 59.6% | 314,243 |
| 60 to 119 min late | 30 min | 91.4% | 6.4% | 145,652 |
| 120+ min late | 31 min | 90.7% | 2.4% | 63,878 |
The full answer
Sector length × departure delay
Every cell reports the median minutes recovered and its own sample. Thin cells remain unpublished rather than borrowing the overall answer.

Method
What “make up time” means here
Does this prove the plane flew faster?
No. We measure gate-to-gate schedule recovery: actual departure delay minus actual arrival delay. The number includes airborne time, taxi time, routing, congestion, and padding already built into the timetable. It answers whether the flight reached the destination closer to schedule. It does not show exactly how the minutes came back.
How do you know the two board rows are the same flight?
We require the same flight number, exact origin and destination, a valid actual clock at both airports, and the nearest scheduled arrival 20 minutes to 20 hours after departure. Cancelled and unresolved legs are excluded.
Why start at 15 minutes late?
Small clock differences are noisy and are not what passengers mean when an airline says it will make up a delay. Published cohorts therefore start at 15 minutes and stop at six hours; extreme or ambiguous clock-wrap cases stay out.
What does “arrived within 15 minutes” mean?
The actual arrival board time was no more than 15 minutes after the scheduled arrival. It is a simple schedule-recovery threshold and does not follow any airline-specific contractual definition of on-time performance.
Keep planning around the delay: will a delayed flight actually be cancelled? how weather maps to real delays, and the global delay board.
