Historical statistics for July 2025 to June 2026, not live status. For today’s AA 310, check with American Airlines.
AA 310 draws a D−. Roughly one flight in two arrives at least 15 minutes late, and the typical late arrival is an hour and a half behind schedule. Build slack into anything you connect to. That rests on 331 flights, with a median arrival 7 minutes late.
The national on-time rate over the same period is 77.6%, so AA 310 runs 18 points behind the country as a whole. Across a thousand flights that is about 184 extra late arrivals.

These figures cover 331 flights between July 2025 and June 2026. Beyond the headline rate, 19.7% 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 310 flies
AA 310 flies DFW to GRR without a single fixed slot. Its most common scheduled departure was 14:52, used on 48 of 331 flights, with 18:30 (45 flights) and 14:25 (42 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 14:52 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AA 310 runs 13 points worse at 59.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
AA 310 quarter by quarter
AA 310 did not run the same all year. Its best quarter was Jul–Sep 2025 at 65.5% on time and its weakest Jan–Mar 2026 at 50.8%, a swing of 15 points on roughly 83 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.
- Jul–Sep 202591 flights65.5%
- Oct–Dec 202588 flights56.5%
- Jan–Mar 202669 flights50.8%
- Apr–Jun 202683 flights62.2%
Scale runs 40% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, AA 310 did best on Friday at 64.0% on time and worst on Sunday at 51.1%. Each day rests on about 47 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 310 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 11,000 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
- 41%Carrier
- 6%National Airspace System
- 2%Extreme weather
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 11,000 reported delay minutes here, that single category outweighs weather by 28 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 10,771 delay minutes reported on AA 310.
Cancellations run at 3.63%, against 1.81% nationally. That is roughly 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 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. 19.7% 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 931 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 one other city pair in the data, including GRR to DFW (234), but none flew often enough under AA 310 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to GRR only.
One caution: this is a thin sample. 331 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 310
For a booking, the cancellation rate is the figure to plan around on AA 310: 3.63% of its 331 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
