Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1310, check with United Airlines.
UA 1310 lands a B, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 317 flights, with a median arrival 7 minutes early.

These figures cover 317 flights between July 2025 and June 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.
Schedule
When UA 1310 flies
UA 1310 flies LGA to ORD without a single fixed slot. Its most common scheduled departure was 10:15, used on 200 of 317 flights, with 10:25 (49 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 10:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 1310 runs 4 points worse at 79.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
UA 1310 quarter by quarter
UA 1310 did not run the same all year. Its best quarter was Jul–Sep 2025 at 94.5% on time and its weakest Oct–Dec 2025 at 71.4%, a swing of 23 points on roughly 79 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.
- Jul–Sep 202555 flights94.5%
- Oct–Dec 202584 flights71.4%
- Jan–Mar 202687 flights77.5%
- Apr–Jun 202691 flights80.9%
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 1310 did best on Tuesday at 86.0% on time and worst on Sunday at 71.1%. Each day rests on about 45 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1310 runs late
One category carries most of the weight here. National Airspace System accounts for 56% of the 5,136 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.
- 56%National Airspace System
- 21%Carrier
- 18%Late-arriving aircraft
- 5%Extreme weather
56% 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 2,888 minutes out of 5,136, against a national NAS share of 21%. The split is drawn from 5,136 delay minutes reported on UA 1310.
Cancellations run at 2.52%, against 1.81% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
7.5% 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 an hour and a half, which a normal layover absorbs.
The 733 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 three other city pairs in the data, including ORD to CMH (68), SNA to ORD (32) and IAH to MIA (11), but none flew often enough under UA 1310 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to ORD only.
One caution: this is a thin sample. 317 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 1310
For a booking, the cancellation rate is the figure to plan around on UA 1310: 2.52% of its 317 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
