Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1170, check with United Airlines.
UA 1170 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 close to two hours on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 6 minutes early.
Set against the rest of the country, UA 1170's record is 5 points better than the US average of 77.6%. That gap is worth roughly 48 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 10.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When UA 1170 flies
UA 1170 flies LAX to HNL without a single fixed slot. Its most common scheduled departure was 17:10, used on 226 of 365 flights, with 17:00 (53 flights) and 17:15 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 17:10226 flights61.9%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 17:10 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 1170 runs 14 points better at 82.4%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
UA 1170 quarter by quarter
Quarter by quarter UA 1170 held fairly steady: 87.0% in Jul–Sep 2025, 81.3% in Oct–Dec 2025, 77.8% in Jan–Mar 2026 and 83.5% 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.
- Jul–Sep 202592 flights87.0%
- Oct–Dec 202592 flights81.3%
- Jan–Mar 202690 flights77.8%
- Apr–Jun 202691 flights83.5%
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, UA 1170 did best on Monday at 88.5% on time and worst on Sunday at 75.0%. Each day rests on about 52 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1170 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 73% of the 7,924 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.
- 73%Late-arriving aircraft
- 24%Carrier
- 3%National Airspace System
73% 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 7,924 reported delay minutes here, that single category outweighs weather by 73 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 7,924 delay minutes reported on UA 1170.
Cancellations are rare at 0.27%, 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 2,556 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 three other city pairs in the data, including ORD to LAX (21), BOS to ORD (12) and HNL to SFO (4), but none flew often enough under UA 1170 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to HNL only.
One caution: this is a thin sample. 365 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 1170
For a booking, read UA 1170 as 82.4% on time with 0.27% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
