These figures cover 320 flights between September 2025 and August 2026. The median arrival is 7 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 1755 quarter by quarter
UA 1755 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.0% on time and its weakest Jul–Sep 2026 at 75.4%, a swing of 15 points on roughly 64 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 1755 did best on Wednesday at 93.5% on time and worst on Sunday at 78.3%. Each day rests on about 46 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late UA 1755 runs when it is late
UA 1755 often beats the schedule: 97 of 318 completed flights, 31%, arrived 15 minutes or more early. The 49 late arrivals split 16 under half an hour, 13 between 30 and 60 minutes, and 20 an hour or more.

Share of 318 completed flights by arrival against schedule.
8 of 41 late departures made up the time and arrived on time, 20% of them. In the other direction, 16 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 ORD.
The worst days
Worst days for UA 1755
The latest arrival of the period was on 29 November 2025, 5 hours 1 minute behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 November 2025 | 5 hours 1 minute | National Airspace System |
| 27 July 2026 | 3 hours 53 minutes | National Airspace System |
| 1 May 2026 | 3 hours 31 minutes | Late-arriving aircraft |

Delay causes
Why UA 1755 runs late
National Airspace System accounts for 72% of the 3,601 delay minutes carriers reported here, and the remaining four split what is left.
- 72%National Airspace System
- 18%Late-arriving aircraft
- 7%Carrier
- 3%Extreme weather
72% 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 2,599 minutes out of 3,601, against a national NAS share of 21%. The split is drawn from 3,601 delay minutes reported on UA 1755.
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
6.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The 1,182 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.
The same number turns up on seven other city pairs in the data, including ORD to DCA (76), IAH to LAS (21) and OKC to IAH (21), but none flew often enough under UA 1755 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to FLL to ORD only.
One caution: this is a thin sample. 320 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 1755
