Historical statistics for July 2025 to June 2026, not live status. For today’s AA 324, check with American Airlines.
AA 324 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 364 flights, with a median arrival 6 minutes early.
The national on-time rate over the same period is 77.6%, so AA 324 runs 6 points behind the country as a whole. Across a thousand flights that is about 63 extra late arrivals.

These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 10.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When AA 324 flies
AA 324 flies DFW to RNO without a single fixed slot. Its most common scheduled departure was 12:08, used on 54 of 364 flights, with 12:12 (44 flights) and 12:19 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 12:08 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AA 324 runs 8 points worse at 71.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
AA 324 quarter by quarter
AA 324 did not run the same all year. Its best quarter was Oct–Dec 2025 at 80.9% on time and its weakest Apr–Jun 2026 at 58.4%, a swing of 23 points on roughly 91 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 324 did best on Monday at 78.4% on time and worst on Sunday at 63.3%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 324 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 6,695 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.
- 51%Late-arriving aircraft
- 27%Carrier
- 11%Extreme weather
- 10%National Airspace System
- 1%Security
51% 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 6,695 reported delay minutes here, that single category outweighs weather by 5 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 6,695 delay minutes reported on AA 324.
Cancellations sit at 1.65% against a national 1.81%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 1,345 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.
AA 324 is not only a DFW to RNO flight. It also flew RNO to DFW (355 flights, 69.5% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 364 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.
