This route carries a cancellation problem, not just a delay problem: 3.3% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 4,728 AUS to DFW flights, of which Envoy Air flew 681 at 79.8% on time.
Best time to fly AUS to DFW: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 89.1% of the time and Tuesday flights 81.5%, against 74.9% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Which airline is most reliable on AUS to DFW
The two carriers here are closely matched: 5 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Envoy Air | 681 | 79.8% | 101 min | 2.79% | B |

| SkyWest Airlinesthin sample | 312 | 65.3% | 137 min | 2.56% | C |
American Airlines cancels 3.3% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Best ways to make this trip
The most reliable ways to fly Austin to Dallas-Fort Worth
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 1 of the top 3 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. AUS → DFWAustin to Dallas-Fort Worth | Envoy Air | 77.6% | 79.8% | 2.79% | 8am–11am, Wed | — |

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 26 points, against 5 points between the best and worst carrier.

Scale runs 55% to 95%.
The 5pm–8pm window is where this operation falls apart: 62.7% on time, against 89.1% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 2pm–5pm window is the busiest, with 1,065 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 17 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
May is the best month on the calendar at 81.4% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. May was the busiest month here, with 427 flights.
Across the week, Tuesday is the strongest day at 81.5% on time and Sunday the weakest at 68.0%, a spread of 14 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 46% of the 125,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 29%Carrier
- 18%National Airspace System
- 7%Extreme weather
- 0%Security
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 125,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 124,585 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 89.1% on time here.
Cancellations run at 3.28%, against 1.89% nationally. That is about one flight in 30 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 stage length
What a delay here actually costs
11.4% 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 190 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 68.1% on time across 4,730 flights, 7 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 7 points of difference.
The sample behind these figures is 4,728 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the delay figures matter less here than the 3.28% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 4,572 completed flights over 12 months sit behind that.
Common questions
AUS to DFW questions
How often is AUS to DFW delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 25.1% of the 4,728 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
Which airline is most reliable on AUS to DFW?
Envoy Air leads at 79.8% on time across 681 flights. American Airlines is at the other end on 75.1%, a gap of 5 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on AUS to DFW?
The 5am–8am departure window is the strongest at 89.1% on time. The 5pm–8pm window is the weakest at 62.7%, 26 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are November delays on AUS to DFW?
November is the weakest month at 64.8% on time, compared with 81.4% in May. Across the year that is 17 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
