This route carries a cancellation problem, not just a delay problem: 3.4% 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 1,070 DFW to GPT flights, with a median arrival 9 minutes early.
Best time to fly DFW to GPT: a 11am–2pm departure, ideally on a Tuesday. Flights in that window arrived on time 93.3% of the time and Tuesday flights 92.1%, against 81.6% for the route overall.
Set against the rest of the country, this route's record is 4 points better than the US average of 77.3%. That gap is worth roughly 43 fewer late arrivals for every thousand flights.

Best ways to make this trip
The most reliable ways to fly Dallas-Fort Worth to Gulfport
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. 2 of the top 3 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. DFW → GPTDallas-Fort Worth to Gulfport | Envoy Air | 83.5% | 85.4% | 2.22% | 11am–2pm, 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 19 points, against half a point between the best and worst carrier.

- 8am–11am269 flights91.4%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 93.3% on time, ahead of 5pm–8pm at 74.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 8pm–5am window is the busiest, with 352 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 26 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 68.4%. February is the strongest month at 94.5%. Moving a flexible trip across that boundary buys 26 points. May was the busiest month here, with 104 flights.
Across the week, Tuesday is the strongest day at 92.1% on time and Sunday the weakest at 75.5%, a spread of 17 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 55% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 24%Carrier
- 14%National Airspace System
- 7%Extreme weather
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 15,457 reported delay minutes.
Cancellations run at 3.36%, 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
8.4% 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 a little over an hour, which a normal layover absorbs.
The 500 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 84.9% on time across 1,074 flights, 3 points above 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. 1,070 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 3.36% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 11am–2pm 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
DFW to GPT questions
How often is DFW to GPT delayed?
Roughly 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 18.4% of the 1,070 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
How reliable is DFW to GPT compared with the rest of the country?
81.6% of flights arrive on time here against a national 77.3%, a difference of 4 points in its favour. That is worth a B− on this site's grading scale.
What time of day has the fewest delays on DFW to GPT?
The 11am–2pm departure window is the strongest at 93.3% on time. The 5pm–8pm window is the weakest at 74.6%, 19 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 DFW to GPT?
May is the weakest month at 68.4% on time, compared with 94.5% in February. Across the year that is 26 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.

Direction matters. DFW to GPT and GPT to DFW are scored separately because they are separate operations, with different departure banks and different aircraft. Compare the return leg.
