| 12 November 2025 | 12 hours 11 minutes | Late-arriving aircraft |
| 3 July 2026 | 4 hours 10 minutes | Late-arriving aircraft |

Delay causes
Why UA 2140 runs late
Late-arriving aircraft accounts for 54% of the 6,114 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 35%Carrier
- 7%National Airspace System
- 4%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,114 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 6,114 delay minutes reported on UA 2140.
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
12.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The same number turns up on six other city pairs in the data, including SAN to IAH (127), IAH to DCA (35) and IAH to LGA (24), but none flew often enough under UA 2140 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. 302 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 2140
For a booking, UA 2140 is a flight to put a long connection behind. 12.3% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
