Historical statistics for July 2025 to June 2026, not live status. For today’s AA 2306, check with American Airlines.
AA 2306 earns an F−, which is as low as this site's scale goes for a reason. Only 49.0% of flights arrive inside the 15-minute window, 29 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 261 flights, with a median arrival 15 minutes late.
The national on-time rate over the same period is 77.6%, so AA 2306 runs 29 points behind the country as a whole. Across a thousand flights that is about 286 extra late arrivals.

These figures cover 261 flights between July 2025 and June 2026. Beyond the headline rate, 23.7% 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 2306 flies
AA 2306 flies DFW to BOS without a single fixed slot. Its most common scheduled departure was 17:25, used on 68 of 261 flights, with 16:12 (30 flights) and 15:57 (30 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 17:25 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AA 2306 runs 19 points worse at 49.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
AA 2306 quarter by quarter
AA 2306 did not run the same all year. Its best quarter was Jan–Mar 2026 at 75.0% on time and its weakest Jul–Sep 2025 at 32.4%, a swing of 43 points on roughly 65 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 202570 flights32.4%
- Oct–Dec 202561 flights46.7%
- Jan–Mar 202645 flights75.0%
- Apr–Jun 202685 flights51.9%
Scale runs 25% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, AA 2306 did best on Friday at 59.0% on time and worst on Sunday at 35.9%. Each day rests on about 37 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 2306 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 54% of the 8,900 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.
- 54%Late-arriving aircraft
- 24%National Airspace System
- 22%Carrier
- 1%Extreme weather
54% 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 8,900 reported delay minutes here, that single category outweighs weather by 54 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 8,900 delay minutes reported on AA 2306.
Cancellations run at 4.21%, against 1.81% nationally. That is about one flight in 25 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. 23.7% 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.
At 1,562 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on four other city pairs in the data, including MSP to PHX (30), PHX to MSP (30) and STT to JFK (16), but none flew often enough under AA 2306 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to BOS only.
One caution: this is a thin sample. 261 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 2306
For a booking, the cancellation rate is the figure to plan around on AA 2306: 4.21% of its 261 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.
