Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with American Airlines.
American on SLC to DFW lands a B, about a point 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 2,202 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate American on SLC to DFW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
American against every carrier on SLC to DFW
American flew 2,202 of the 3,870 flights on SLC to DFW, most of the route. Its 78.7% on time is about level with the route as a whole at 79.8%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from Delta at 81.6% to Envoy at 77.8%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Book the early departure. Flights leaving between 5am–8am arrive on time 90.0% of the time, against 59.6% for the afternoon window. That is 30 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 731 flights scheduled in it.

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 46% of the 47,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 44%Carrier
- 9%National Airspace System
- 2%Extreme weather
- 0%Security
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 47,000 reported delay minutes here, that single category outweighs weather by 26 to one. The split is drawn from 47,474 reported delay minutes.
The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 21,000 of the 47,000 delay minutes reported here.
Cancellations run at 2.82%, 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 costs
8.8% 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 989 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 61.7% on time across 2,203 flights, 17 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 17 points of difference.
The sample behind these figures is 2,202 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 American on SLC to DFW
Put together: the delay figures matter less here than the 2.82% cancellation rate. A late arrival costs you close to two hours; 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. 2,126 completed flights over 12 months sit behind that.
