These figures cover 323 flights between September 2025 and August 2026. The median arrival is 12 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 6 December 2025, 8 hours 47 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across December, July, March and May, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 December 2025 | 8 hours 47 minutes | Late-arriving aircraft |
| 10 July 2026 | 4 hours 21 minutes | Carrier |
| 16 March 2026 | 2 hours 59 minutes | National Airspace System |

Delay causes
Why UA 2105 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,430 reported delay minutes.
- 38%National Airspace System
- 37%Late-arriving aircraft
- 23%Carrier
- 1%Extreme weather
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,430 reported delay minutes here, that single category outweighs weather by 27 to one. The split is drawn from 2,430 delay minutes reported on UA 2105.
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
Badly late arrivals are rare here: only 4.3% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The same number turns up on three other city pairs in the data, including IAH to MIA (92), STL to IAH (1) and KOA to SFO (1), but none flew often enough under UA 2105 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSY to IAH only.
One caution: this is a thin sample. 323 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 2105
For a booking, UA 2105 has one of the better records a US domestic flight can show: 90.4% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
