These figures cover 275 flights between September 2025 and August 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.

Across the year

UA 1499 quarter by quarter

UA 1499 did not run the same all year. Its best quarter was Apr–Jun 2026 at 93.3% on time and its weakest Oct–Dec 2025 at 76.2%, a swing of 17 points on roughly 92 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 271 completed flights by arrival against schedule.

10 of 36 late departures made up the time and arrived on time, 28% of them. In the other direction, 16 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 EWR.

Delay causes

Why UA 1499 runs late

National Airspace System accounts for 60% of the 3,525 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System
60%
Late-arriving aircraft
20%
Carrier
19%

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 2,123 minutes out of 3,525, against a national NAS share of 21%. The split is drawn from 3,525 delay minutes reported on UA 1499.

Cancellations sit at 1.09% against a national 1.89%, which is ordinary. Diversions add another 0.36%.

Connections and routes

What a delay on this flight costs

5.2% of arrivals land an hour or more late, close to the national 8.3%, so 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.

At 1,504 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 seven other city pairs in the data, including CID to ORD (40), EWR to FLL (32) and LAS to IAH (23), but none flew often enough under UA 1499 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to AUS to EWR only.

One caution: this is a thin sample. 275 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.
