These figures cover 298 flights between July 2025 and June 2026. The median arrival is 14 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.

Schedule

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 274 of the 298 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 1392 runs 8 points better at 91.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 1392 next to MSY to IAD

Across the year

UA 1392 quarter by quarter

Quarter by quarter UA 1392 held fairly steady: 91.8% in Jul–Sep 2025, 91.6% in Oct–Dec 2025, 92.5% in Jan–Mar 2026 and 91.9% in Apr–Jun 2026. A spread of about a point is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202573 flights91.8%
Oct–Dec 202583 flights91.6%
Jan–Mar 202668 flights92.5%

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1392 ranged from 87.8% on Sunday to 96.2% on Friday. With about 43 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 1392 runs late

One category carries most of the weight here. Carrier accounts for 77% of the 1,660 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

3%

The largest share of delay minutes, 77%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,279 of the 1,660 delay minutes reported here. The split is drawn from 1,660 delay minutes reported on UA 1392.

Cancellations are rare at 0.34%, below the national 1.81% 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 3.7% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on six other city pairs in the data, including IAD to BOS (118), BOS to IAH (91) 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. 298 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: 91.9% on time and 0.34% cancelled. That is a base rate, not a promise about any single day.
