AA 2066 sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 251 flights, with a median arrival 4 minutes early.

These figures cover 251 flights between July 2025 and June 2026. The median arrival is 4 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Schedule
When AA 2066 flies
AA 2066 flies SLC to DFW without a single fixed slot. Its most common scheduled departure was 09:15, used on 42 of 251 flights, with 12:10 (36 flights) and 09:21 (28 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AA 2066 runs 10 points worse at 74.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route
AA 2066 next to SLC to DFW

Across the year
AA 2066 quarter by quarter
AA 2066 did not run the same all year. Its best quarter was Jan–Mar 2026 at 81.4% on time and its weakest Jul–Sep 2025 at 61.6%, a swing of 20 points on roughly 84 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, AA 2066 ranged from 67.6% on Thursday to 78.4% on Wednesday. With about 36 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why AA 2066 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 4,157 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 57%Late-arriving aircraft
- 29%Carrier
- 13%National Airspace System
- 1%Extreme weather
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,157 reported delay minutes here, that single category outweighs weather by 57 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,157 delay minutes reported on AA 2066.
Cancellations run at 2.79%, against 1.81% 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 routes
What a delay on this flight costs
7.5% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on five other city pairs in the data, including DFW to SLC (63), ORD to ELP (44) and MCO to ORD (41), but none flew often enough under AA 2066 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to DFW only.
One caution: this is a thin sample. 251 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 AA 2066
For a booking, the cancellation rate is the figure to plan around on AA 2066: 2.79% of its 251 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
