Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2410, check with United Airlines.

UA 2410 lands a B+, 5 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 an hour and a half on average. That is a workable record, not a spotless one. That rests on 300 flights, with a median arrival 8 minutes early.

Set against the rest of the country, UA 2410's record is 5 points better than the US average of 77.6%. That gap is worth roughly 49 fewer late arrivals for every thousand flights.

These figures cover 300 flights between July 2025 and June 2026. The median arrival is 8 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 2410 flies

UA 2410 flies IAD to SLC without a single fixed slot. Its most common scheduled departure was 17:55, used on 116 of 300 flights, with 17:50 (94 flights) and 17:44 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 17:55 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2410 runs 14 points better at 82.5%. 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 2410 next to IAD to SLC

Every carrier on IAD to SLC combined arrived on time 84.0% of the time across 714 flights, so UA 2410 is 2 points behind it. Across its whole network United Airlines managed 79.0%, which this flight beats by 4 points.

Across the year

UA 2410 quarter by quarter

Quarter by quarter UA 2410 held fairly steady: 83.7% in Jul–Sep 2025, 84.0% in Oct–Dec 2025, 79.8% in Jan–Mar 2026 and 83.3% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

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

By weekday, UA 2410 did best on Saturday at 93.0% on time and worst on Thursday at 72.1%. Each day rests on about 43 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2410 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 55% of the 4,456 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.

55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,456 reported delay minutes here, that single category outweighs weather by 35 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,456 delay minutes reported on UA 2410.

Cancellations are rare at 0.67%, 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

6.7% 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 an hour and a half, which a normal layover absorbs.

At 1,827 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on four other city pairs in the data, including TPA to IAD (24), DEN to LGA (18) and LAS to IAH (16), but none flew often enough under UA 2410 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAD to SLC only.

One caution: this is a thin sample. 300 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 2410

For a booking, read UA 2410 as 82.5% on time with 0.67% cancelled over 300 flights. Those are rates from the past twelve months, not a forecast for any particular day.
