These figures cover 273 flights between September 2025 and August 2026. The median arrival is 11 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.

Across the year
UA 1730 quarter by quarter
UA 1730 did not run the same all year. Its best quarter was Jan–Mar 2026 at 93.5% on time and its weakest Jul–Sep 2026 at 83.0%, a swing of 11 points on roughly 68 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, UA 1730 did best on Saturday at 94.7% on time and worst on Friday at 82.5%. Each day rests on about 39 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 November 2025 | 8 hours 33 minutes | Carrier |
| 9 July 2026 | 8 hours | Carrier |
| 29 November 2025 | 4 hours 53 minutes | Late-arriving aircraft |

Delay causes
Why UA 1730 runs late
Carrier accounts for 55% of the 2,468 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 32%Late-arriving aircraft
- 13%National Airspace System
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,352 of the 2,468 delay minutes reported here. The split is drawn from 2,468 delay minutes reported on UA 1730.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are 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 2.9% 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 2,218 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 six other city pairs in the data, including SEA to LAX (110), LAX to SAN (56) and SMF to LAX (36), but none flew often enough under UA 1730 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to MCO only.
One caution: this is a thin sample. 273 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 1730
For a booking, UA 1730 has one of the better records a US domestic flight can show: 89.7% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
