Across the year
AA 310 quarter by quarter
AA 310 did not run the same all year. Its best quarter was Jul–Sep 2026 at 72.1% on time and its weakest Jan–Mar 2026 at 50.8%, a swing of 21 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.

By weekday, AA 310 did best on Saturday at 73.8% on time and worst on Sunday at 51.0%. Each day rests on about 47 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

The latest arrival of the period was on 24 November 2025, 12 hours 39 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 November 2025 | 12 hours 39 minutes | Carrier |
| 22 December 2025 | 4 hours 49 minutes | Late-arriving aircraft |
| 23 March 2026 | 4 hours 42 minutes | Carrier |
| 8 March 2026 | 4 hours 22 minutes | Late-arriving aircraft |

Delay causes
Why AA 310 runs late
Late-arriving aircraft accounts for 51% of the 9,597 delay minutes carriers reported here, and the remaining four split what is left.
- 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. Across 9,597 reported delay minutes here, that single category outweighs weather by 26 to one. The split is drawn from 9,597 delay minutes reported on AA 310.
Cancellations run at 2.71%, 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 routes
What a delay on this flight costs
16.5% 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 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.
The same number turns up on one other city pair in the data, including GRR to DFW (235), 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. 332 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: 2.71% of its 332 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.
