These figures cover 329 flights between September 2025 and August 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

The latest arrival of the period was on 7 August 2026, 3 hours 19 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 August 2026 | 3 hours 19 minutes | Carrier |
| 16 March 2026 | 2 hours 55 minutes | Late-arriving aircraft |
| 12 November 2025 | 2 hours 50 minutes | Late-arriving aircraft |

Delay causes
Why UA 2474 runs late
Carrier accounts for 53% of the 2,820 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 35%Late-arriving aircraft
- 11%National Airspace System
- 2%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,820 reported delay minutes here, that single category outweighs weather by 21 to one. The split is drawn from 2,820 delay minutes reported on UA 2474.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
6.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The same number turns up on seven other city pairs in the data, including PHL to IAH (148), FLL to IAH (35) and ATL to IAH (27), but none flew often enough under UA 2474 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to MSY only.
One caution: this is a thin sample. 329 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking UA 2474
