These figures cover 364 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.

Arrival by arrival
How late UA 1740 runs when it is late
UA 1740 often beats the schedule: 129 of 362 completed flights, 36%, arrived 15 minutes or more early. The 29 late arrivals split 13 under half an hour, 10 between 30 and 60 minutes, and 6 an hour or more.

Share of 362 completed flights by arrival against schedule.
A late pushback is often recovered here: of 20 departures that left 15 minutes late or more, 10 still arrived on time. In the other direction, 19 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at RSW.
The worst days
Worst days for UA 1740
The latest arrival of the period was on 12 July 2026, 2 hours 12 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across July, January, March, September and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 July 2026 | 2 hours 12 minutes | Late-arriving aircraft |
| 17 January 2026 | 1 hour 57 minutes | Carrier |
| 16 March 2026 | 1 hour 51 minutes | National Airspace System |

Delay causes
Why UA 1740 runs late
National Airspace System accounts for 62% of the 1,286 delay minutes carriers reported here, and the remaining four split what is left.
- 62%National Airspace System
- 17%Carrier
- 11%Late-arriving aircraft
- 10%Extreme weather
62% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 792 minutes out of 1,286, against a national NAS share of 21%. The split is drawn from 1,286 delay minutes reported on UA 1740.
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 1.7% 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.
The 1,120 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.
Every one of the 364 flights under UA 1740 in the data flew ORD to RSW. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 364 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 1740
For a booking, UA 1740 has one of the better records a US domestic flight can show: 92.0% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
