These figures cover 365 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.

The worst days
Worst days for UA 1749
The latest arrival of the period was on 16 March 2026, 2 hours 47 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 March 2026 | 2 hours 47 minutes | Carrier |
| 28 May 2026 | 2 hours 40 minutes | Late-arriving aircraft |
| 25 August 2026 | 2 hours 9 minutes | Carrier |
| 19 July 2026 | 1 hour 25 minutes | Late-arriving aircraft |
| 24 February 2026 | 1 hour 3 minutes | Late-arriving aircraft |
Delay causes
Why UA 1749 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 1,796 reported delay minutes.
- 41%Carrier
- 36%Late-arriving aircraft
- 23%National Airspace System
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,796 reported delay minutes here, that single category outweighs weather by 36 to one. The split is drawn from 1,796 delay minutes reported on UA 1749.
Cancellations are rare at 0.55%, 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 1.4% 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.
At 2,338 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 two other city pairs in the data, including AUS to SFO (61) and EWR to AUS (20), but none flew often enough under UA 1749 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to OGG 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 1749
For a booking, UA 1749 has one of the better records a US domestic flight can show: 88.2% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
