These figures cover 364 flights between July 2025 and June 2026. The median arrival is 12 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 1740 flies

UA 1740 flies ORD to RSW without a single fixed slot. Its most common scheduled departure was 07:05, used on 83 of 364 flights, with 07:15 (62 flights) and 07:25 (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 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 1740 runs 4 points better at 92.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, UA 1740 ranged from 86.5% on Sunday to 98.1% on Tuesday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 1740 runs late

One category carries most of the weight here. National Airspace System accounts for 59% of the 1,257 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.

Carrier

Extreme weather
10%
Late-arriving aircraft
1%

59% 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 746 minutes out of 1,257, against a national NAS share of 21%. The split is drawn from 1,257 delay minutes reported on UA 1740.

Cancellations are rare at 0.27%, below the national 1.81% 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 1.9% land an hour or more behind schedule, against 8.1% 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. 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.

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: 92.8% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
