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 1,175 GSP to DFW flights, with a median arrival 6 minutes early.
Best time to fly GSP to DFW: a 5am–8am departure, ideally on a Thursday. Flights in that window arrived on time 83.1% of the time and Thursday flights 81.2%, against 76.4% 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 Greer 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. GSP → DFWGreer to Dallas-Fort Worth | American Airlines | 71.9% | 74.4% | 3.31% | 5am–8am, Thu | — |
| 2. AVL → DFWAsheville to Dallas-Fort Worth | American Airlines | 60.7% | 62.6% | 3.01% | 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 5pm–8pm window is where this operation falls apart: 61.4% on time, against 83.1% 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 365 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 15 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.
July is the worst month at 68.9% on time, 15 points below March, the best at 83.7%. 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. July was the busiest month here, with 120 flights.
Across the week, Thursday is the strongest day at 81.2% on time and Sunday the weakest at 70.3%, a spread of 11 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 48% of the 26,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 36%Carrier
- 9%National Airspace System
- 7%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 26,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 25,844 reported delay minutes.
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 9,257 of the 26,000 delay minutes reported here.
Cancellations run at 2.55%, against 1.89% nationally. That is about 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
10.6% 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 862 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 73.3% on time across 1,173 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.
The sample behind these figures is 1,175 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. March runs 83.7% on time and July 68.9%, a swing of 15 points. If the dates move at all, move them out of July before you think about anything else. 1,139 completed flights over 12 months sit behind that.
Common questions
GSP to DFW questions
How often is GSP 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 23.6% of the 1,175 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is GSP to DFW compared with the rest of the country?
76.4% 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 GSP to DFW?
The 5am–8am departure window is the strongest at 83.1% on time. The 5pm–8pm window is the weakest at 61.4%, 22 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 July delays on GSP to DFW?
July is the weakest month at 68.9% on time, compared with 83.7% in March. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
