This route lands a B, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 3,543 BNA to DFW flights, with a median arrival 8 minutes early.
Best time to fly BNA to DFW: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 87.1% of the time and Tuesday flights 82.8%, against 76.3% 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.

Best ways to make this trip
The most reliable ways to fly Nashville 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 2 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. BNA → DFWNashville to Dallas-Fort Worth | American Airlines | 75.1% | 77.2% | 2.72% | 5am–8am, Tue | AA 2787 05:00 |
| 2. BNA → DALNashville to Dallas | Southwest Airlines | 74.6% | 75.4% | 1.05% | 5am–8am, 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.

The 5pm–8pm window is where this operation falls apart: 60.6% on time, against 87.1% 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 5am–8am window is the busiest, with 864 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 14 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.
Delays peak in May, when the on-time rate falls to 69.4%. February is the strongest month at 83.5%. Moving a flexible trip across that boundary buys 14 points. June was the busiest month here, with 327 flights.
Across the week, Tuesday is the strongest day at 82.8% on time and Sunday the weakest at 70.3%, a spread of 13 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 45% of the 77,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 30%Carrier
- 21%National Airspace System
- 4%Extreme weather
- 0%Security
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 77,000 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 77,119 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 87.1% on time here.
Cancellations run at 2.96%, against 1.89% nationally. That is roughly 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
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 an hour and a half, which a normal layover absorbs.
The 631 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 67.1% on time across 3,544 flights, 9 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 9 points of difference.
The sample behind these figures is 3,543 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 2.96% cancellation rate. A late arrival costs you an hour and a half; 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. 3,426 completed flights over 12 months sit behind that.
Common questions
BNA to DFW questions
How often is BNA 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 23.7% of the 3,543 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is BNA to DFW compared with the rest of the country?
76.3% of flights arrive on time here against a national 77.3%, a difference of about a point against it. That is worth a B on this site's grading scale.
What time of day has the fewest delays on BNA to DFW?
The 5am–8am departure window is the strongest at 87.1% on time. The 5pm–8pm window is the weakest at 60.6%, 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 May delays on BNA to DFW?
May is the weakest month at 69.4% on time, compared with 83.5% in February. Across the year that is 14 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
