AA 1726 lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 276 flights, with a median arrival 12 minutes early.

These figures cover 276 flights between July 2025 and June 2026. Beyond the headline rate, 9.3% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When AA 1726 flies

AA 1726 flies AUS to ORD without a single fixed slot. Its most common scheduled departure was 08:00, used on 98 of 276 flights, with 06:42 (42 flights) and 07:45 (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 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AA 1726 runs 4 points worse at 80.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AA 1726 quarter by quarter

Quarter by quarter AA 1726 held fairly steady: 80.0% in Jul–Sep 2025, 82.8% in Oct–Dec 2025 and 75.3% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AA 1726 did best on Thursday at 89.2% on time and worst on Saturday at 70.3%. Each day rests on about 39 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 1726 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 55% of the 5,906 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.

55%
Carrier
33%
National Airspace System
10%
Extreme weather
2%

55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,906 reported delay minutes here, that single category outweighs weather by 29 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,906 delay minutes reported on AA 1726.

Cancellations sit at 1.81% against a national 1.81%, which is ordinary. Diversions add another 0.72%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.3% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 977 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 four other city pairs in the data, including TPA to ORD (30), ORD to AUS (7) and DFW to LGA (4), but none flew often enough under AA 1726 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to AUS to ORD only.

One caution: this is a thin sample. 276 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 AA 1726

For a booking, read AA 1726 as 80.3% on time with 1.81% cancelled over 276 flights. Those are rates from the past twelve months, not a forecast for any particular day.
