This route carries a cancellation problem, not just a delay problem: 3.7% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,079 TLH to DFW flights, with a median arrival 12 minutes early.
Best time to fly TLH to DFW: a 8am–11am departure, ideally on a Friday. Flights in that window arrived on time 93.0% of the time and Friday flights 84.6%, against 78.9% 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.

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 28 points, against half a point between the best and worst carrier.

Scale runs 55% to 100%.
Book the morning departure. Flights leaving between 8am–11am arrive on time 93.0% of the time, against 65.4% for the evening window. That is 28 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 321 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 21 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 March, when the on-time rate falls to 67.1%. August is the strongest month at 88.2%. Moving a flexible trip across that boundary buys 21 points. March was the busiest month here, with 93 flights.
Across the week, Friday is the strongest day at 84.6% on time and Sunday the weakest at 72.8%, a spread of 12 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 50% of the 25,000 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 36%Carrier
- 8%Extreme weather
- 7%National Airspace System
- 0%Security
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 25,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 25,279 reported delay minutes.
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 8,992 of the 25,000 delay minutes reported here.
Cancellations run at 3.71%, against 1.89% nationally. That is about one flight in 25 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
12.1% 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.
The 767 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 75.5% on time across 1,078 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 1,079 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 this route
Put together: the delay figures matter less here than the 3.71% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 1,032 completed flights over 12 months sit behind that.
Common questions
TLH to DFW questions
How often is TLH 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 21.1% of the 1,079 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
How reliable is TLH to DFW compared with the rest of the country?
78.9% of flights arrive on time here against a national 77.3%, a difference of 2 points in its favour. That is worth a B− on this site's grading scale.
What time of day has the fewest delays on TLH to DFW?
The 8am–11am departure window is the strongest at 93.0% on time. The 5pm–8pm window is the weakest at 65.4%, 28 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 March delays on TLH to DFW?
March is the weakest month at 67.1% on time, compared with 88.2% in August. Across the year that is 21 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
