Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1657, check with United Airlines.

UA 1657 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 280 flights, with a median arrival 7 minutes early.

Set against the rest of the country, UA 1657's record is 6 points better than the US average of 77.6%. That gap is worth roughly 62 fewer late arrivals for every thousand flights.

These figures cover 280 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 1657 flies

UA 1657 is scheduled to leave Chicago (ORD) at 07:00 local time and reach New York (LGA) at 10:18. That slot held for 280 of the 280 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

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 6 points worse at 83.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 1657 next to ORD to LGA

Across the year

UA 1657 quarter by quarter

Quarter by quarter UA 1657 held fairly steady: 87.9% in Jul–Sep 2025, 78.7% in Oct–Dec 2025 and 86.8% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, UA 1657 did best on Friday at 89.7% on time and worst on Sunday at 75.6%. Each day rests on about 40 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1657 runs late

One category carries most of the weight here. National Airspace System accounts for 46% of the 2,528 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.

  • National Airspace System
    46%
  • Carrier
    32%
  • Late-arriving aircraft
    21%
  • Extreme weather
    1%

46% 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 1,159 minutes out of 2,528, against a national NAS share of 21%. The split is drawn from 2,528 delay minutes reported on UA 1657.

Cancellations are rare at 0.71%, 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

5.0% 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 about an hour, 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 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. 280 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

For a booking, read UA 1657 as 83.8% on time with 0.71% cancelled over 280 flights. Those are rates from the past twelve months, not a forecast for any particular day.
