This route lands a B, 3 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 2,196 BHM to DFW flights, of which Envoy Air flew 708 at 81.7% on time.
Best time to fly BHM to DFW: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 89.0% of the time and Tuesday flights 85.9%, against 80.1% 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 BHM to DFW
The two carriers here are closely matched: 3 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.

PSA Airlines cancels 3.8% 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 Birmingham 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. BHM → DFWBirmingham to Dallas-Fort Worth | Envoy Air | 80.5% | 81.7% | 1.41% | 5am–8am, Tue | — |

| 3. BHM → DFWBirmingham to Dallas-Fort Worth | PSA Airlines | 75.3% | 78.3% | 3.84% | 5am–8am, Tue | — |
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 23 points, against 3 points between the best and worst carrier.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.0% of the time, against 65.9% for the afternoon window. That is 23 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 699 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.
June is the worst month at 70.5% on time, 17 points below February, the best at 87.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. May was the busiest month here, with 209 flights.
Across the week, Tuesday is the strongest day at 85.9% on time and Saturday the weakest at 75.2%, a spread of 11 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 48% of the 45,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 28%Carrier
- 17%Extreme weather
- 7%National Airspace System
Extreme weather accounts for 17% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.8 times the usual weather exposure. The split is drawn from 45,161 reported delay minutes.
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 45,000 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 2.78%, against 1.89% nationally. That is roughly one flight in 40 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
8.9% 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 close to two hours, which a normal layover absorbs.
The 597 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 return leg is a different operation and performs like one: it runs 75.2% on time across 2,197 flights, 5 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 5 points of difference.
The sample behind these figures is 2,196 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 calendar is the biggest lever here, not the carrier or the hour. February runs 87.0% on time and June 70.5%, a swing of 17 points. If the dates move at all, move them out of June before you think about anything else. 2,125 completed flights over 12 months sit behind that.
Common questions
BHM to DFW questions
How often is BHM to DFW delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.9% of the 2,196 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 BHM to DFW?
Envoy Air leads at 81.7% on time across 708 flights. PSA Airlines is at the other end on 78.3%, a gap of 3 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 BHM to DFW?
The 5am–8am departure window is the strongest at 89.0% on time. The 2pm–5pm window is the weakest at 65.9%, 23 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 June delays on BHM to DFW?
June is the weakest month at 70.5% on time, compared with 87.0% in February. 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.
