These figures cover 284 flights between September 2025 and August 2026. The median arrival is 13 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.

When UA 1392 flies
UA 1392 is scheduled to leave New Orleans (MSY) at 08:00 local time and reach Washington (IAD) at 11:25. That slot held for 260 of the 284 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 July 2026 | 10 hours 11 minutes | Carrier |
| 30 November 2025 | 3 hours 30 minutes | Carrier |

Delay causes
Why UA 1392 runs late
Carrier accounts for 77% of the 1,906 delay minutes carriers reported here, and the remaining four split what is left.
- 77%Carrier
- 14%National Airspace System
- 6%Extreme weather
- 3%Late-arriving aircraft
The largest share of delay minutes, 77%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,475 of the 1,906 delay minutes reported here. The split is drawn from 1,906 delay minutes reported on UA 1392.
Cancellations are rare at 0.35%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is 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 3.5% 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 955 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on six other city pairs in the data, including IAD to BOS (180), BOS to IAH (152) and SMF to SFO (2), but none flew often enough under UA 1392 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSY to IAD only.
One caution: this is a thin sample. 284 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 1392
For a booking, UA 1392 has one of the better records a US domestic flight can show: 92.6% on time and 0.35% cancelled. That is a base rate, not a promise about any single day.
