These figures cover 271 flights between July 2025 and June 2026. The median arrival is 9 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.
Schedule
When UA 1755 flies
UA 1755 flies FLL to ORD without a single fixed slot. Its most common scheduled departure was 12:26, used on 109 of 271 flights, with 12:31 (53 flights) and 12:28 (53 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 12:26 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1755 runs 8 points better at 86.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

By weekday, UA 1755 did best on Wednesday at 94.9% on time and worst on Friday at 78.4%. Each day rests on about 39 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1755 runs late
One category carries most of the weight here. National Airspace System accounts for 60% of the 2,544 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.
- 60%National Airspace System
- 28%Late-arriving aircraft
- 9%Carrier
- 3%Extreme weather
60% 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 1,524 minutes out of 2,544, against a national NAS share of 21%. The split is drawn from 2,544 delay minutes reported on UA 1755.
Cancellations are rare at 0.00%, below the national 1.81% 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
5.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on nine other city pairs in the data, including ORD to DCA (114), TVC to ORD (49) and DCA to IAH (26), 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. 271 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
For a booking, UA 1755 has one of the better records a US domestic flight can show: 86.7% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
