Share of 262 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 90 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 60 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 ORD.

Delay causes
Why UA 2299 runs late
National Airspace System accounts for 47% of the 12,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%National Airspace System
- 45%Late-arriving aircraft
- 8%Carrier
- 0%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 12,000 reported delay minutes here, that single category outweighs weather by 45 to one. The split is drawn from 12,094 delay minutes reported on UA 2299.
Cancellations run at 5.76%, against 1.89% nationally. That is roughly one flight in fifteen 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
26.7% 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.
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 DFW to ORD (41), ORD to MCI (18) and DEN to BWI (7), but none flew often enough under UA 2299 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. 278 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 2299
For a booking, the cancellation rate is the figure to plan around on UA 2299: 5.76% of its 278 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.
