These figures cover 279 flights between September 2025 and August 2026. The median arrival is 6 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.

When UA 1657 flies
UA 1657 is scheduled to leave Chicago (ORD) at 07:00 local time and reach New York (LGA) at 10:17. That slot held for 279 of the 279 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 1657 runs 8 points worse at 81.2%. 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 1657 quarter by quarter
UA 1657 did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.8% on time and its weakest Jul–Sep 2026 at 76.7%, a swing of 10 points on roughly 70 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 1657 ranged from 76.3% on Thursday to 87.2% on Friday. With about 40 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Share of 277 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 31 departures that left 15 minutes late or more, only 1 made it up before arrival. In the other direction, 22 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 LGA.
The worst days
Worst days for UA 1657
The latest arrival of the period was on 14 December 2025, 4 hours 21 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 December 2025 | 4 hours 21 minutes | National Airspace System |
| 30 November 2025 | 3 hours 22 minutes | Carrier |

Delay causes
Why UA 1657 runs late
National Airspace System accounts for 53% of the 2,640 delay minutes carriers reported here, and the remaining four split what is left.
- 53%National Airspace System
- 28%Carrier
- 18%Late-arriving aircraft
- 1%Extreme weather
53% 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 1,412 minutes out of 2,640, against a national NAS share of 21%. The split is drawn from 2,640 delay minutes reported on UA 1657.
Cancellations are rare at 0.72%, 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 4.3% 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 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.
The same number turns up on three other city pairs in the data, including ORD to MSN (53), IAH to PBI (24) and EGE to ORD (21), but none flew often enough under UA 1657 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to LGA only.
One caution: this is a thin sample. 279 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 1657
