Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1206, check with American Airlines.

AA 1206 lands a B, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 359 flights, with a median arrival 9 minutes early.

Set against the rest of the country, AA 1206's record is 4 points better than the US average of 77.6%. That gap is worth roughly 41 fewer late arrivals for every thousand flights.

These figures cover 359 flights between July 2025 and June 2026. The median arrival is 9 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 1206 flies

AA 1206 flies DFW to BOS without a single fixed slot. Its most common scheduled departure was 07:00, used on 94 of 359 flights, with 08:24 (44 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 1206 runs 8 points worse at 81.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AA 1206 quarter by quarter

AA 1206 did not run the same all year. Its best quarter was Apr–Jun 2026 at 88.8% on time and its weakest Jul–Sep 2025 at 69.4%, a swing of 19 points on roughly 90 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.

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, AA 1206 did best on Sunday at 92.0% on time and worst on Monday at 73.5%. Each day rests on about 51 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 1206 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,484 reported delay minutes.

Late-arriving aircraft
37%
Carrier
36%
National Airspace System
22%
Extreme weather
6%

37% 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 4,484 reported delay minutes here, that single category outweighs weather by 6 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 4,484 delay minutes reported on AA 1206.

Cancellations run at 2.51%, against 1.81% 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

6.0% 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.

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 one other city pair in the data, including BOS to DFW (22), but none flew often enough under AA 1206 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. 359 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 1206

For a booking, the cancellation rate is the figure to plan around on AA 1206: 2.51% of its 359 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.
