Across the year

UA 2168 quarter by quarter

UA 2168 did not run the same all year. Its best quarter was Oct–Dec 2025 at 71.7% on time and its weakest Jul–Sep 2026 at 52.0%, a swing of 20 points on roughly 72 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.

Share of 277 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 76 departures that left 15 minutes late or more, only 4 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.

Delay causes

Why UA 2168 runs late

National Airspace System accounts for 60% of the 7,796 delay minutes carriers reported here, and the remaining four split what is left.

Carrier

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 4,675 minutes out of 7,796, against a national NAS share of 21%. The split is drawn from 7,796 delay minutes reported on UA 2168.

Cancellations sit at 2.10% against a national 1.89%, which is ordinary. Diversions add another 1.05%.

Connections and routes

What a delay on this flight costs

17.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

At 1,620 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on three other city pairs in the data, including IAH to DEN (180), SFO to IAH (159) and ORD to FLL (37), but none flew often enough under UA 2168 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to LGA only.

One caution: this is a thin sample. 286 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 2168

For a booking, UA 2168 is a flight to put a long connection behind. 17.3% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
