UA 1499 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 254 flights, with a median arrival 6 minutes early.

Set against the rest of the country, UA 1499's record is 7 points better than the US average of 77.6%. That gap is worth roughly 65 fewer late arrivals for every thousand flights.

These figures cover 254 flights between July 2025 and June 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.

Schedule

When UA 1499 flies

UA 1499 flies AUS to EWR without a single fixed slot. Its most common scheduled departure was 11:20, used on 34 of 254 flights, with 10:40 (33 flights) and 10:55 (32 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 11:20 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1499 runs 5 points better at 84.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

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 85 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 1499 did best on Wednesday at 89.5% on time and worst on Friday at 76.3%. Each day rests on about 36 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1499 runs late

One category carries most of the weight here. National Airspace System accounts for 61% of the 3,474 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
61%
Late-arriving aircraft
20%
Carrier
19%

61% 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 3,474, against a national NAS share of 21%. The split is drawn from 3,474 delay minutes reported on UA 1499.

Cancellations sit at 1.18% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.6% 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 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 eight other city pairs in the data, including EWR to SRQ (63), 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. 254 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.
