Historical statistics for July 2025 to June 2026, not live status. For today’s UA 689, check with United Airlines.

UA 689 lands a B+, 4 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 340 flights, with a median arrival 7 minutes early.

Set against the rest of the country, UA 689's record is 4 points better than the US average of 77.6%. That gap is worth roughly 44 fewer late arrivals for every thousand flights.

These figures cover 340 flights between July 2025 and June 2026. The median arrival is 7 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 689 flies

UA 689 flies IAD to MCO without a single fixed slot. Its most common scheduled departure was 22:33, used on 73 of 340 flights, with 22:15 (64 flights) and 22:22 (63 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 22:33 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and UA 689 runs 12 points better at 82.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

UA 689 next to IAD to MCO

Every carrier on IAD to MCO combined arrived on time 81.7% of the time across 2,176 flights, so UA 689 is about level with it. United flew 1,897 flights on the same city pair under all its flight numbers, including this one, and those ran 83.0% on time. Across its whole network United Airlines managed 79.0%, which this flight beats by 3 points.

Across the year

UA 689 quarter by quarter

Quarter by quarter UA 689 held fairly steady: 77.2% in Jul–Sep 2025, 81.1% in Oct–Dec 2025, 85.7% in Jan–Mar 2026 and 84.8% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Oct–Dec 202590 flights81.1%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, UA 689 did best on Tuesday at 95.5% on time and worst on Sunday at 74.5%. Each day rests on about 49 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 689 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 3,514 reported delay minutes.

Carrier
40%
Late-arriving aircraft
32%
National Airspace System
23%
Extreme weather
5%

The largest share of delay minutes, 40%, 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 1,414 of the 3,514 delay minutes reported here. The split is drawn from 3,514 delay minutes reported on UA 689.

Cancellations are rare at 0.59%, 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

6.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 758 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 seven other city pairs in the data, including RDU to IAD (37), LAX to IAD (36) and SFO to IAD (19), but none flew often enough under UA 689 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAD to MCO only.

One caution: this is a thin sample. 340 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 689

For a booking, read UA 689 as 82.0% on time with 0.59% cancelled over 340 flights. Those are rates from the past twelve months, not a forecast for any particular day.
