Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1177, check with American Airlines.
AA 1177 lands a B, about a point worse than the national rate of 77.6%. About one flight in four 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 364 flights, with a median arrival 9 minutes early.

These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% 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 1177 flies
AA 1177 flies DCA to DFW without a single fixed slot. Its most common scheduled departure was 12:59, used on 45 of 364 flights, with 13:45 (44 flights) and 14:14 (41 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 12:59 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AA 1177 runs 2 points worse at 76.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.
Against the route
AA 1177 next to DCA to DFW

Across the year
AA 1177 quarter by quarter
Quarter by quarter AA 1177 held fairly steady: 73.9% in Jul–Sep 2025, 76.9% in Oct–Dec 2025, 77.6% in Jan–Mar 2026 and 78.2% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AA 1177 did best on Saturday at 85.7% on time and worst on Sunday at 67.3%. Each day rests on about 52 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 1177 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 6,610 reported delay minutes.
- 34%Late-arriving aircraft
- 34%Carrier
- 18%National Airspace System
- 14%Extreme weather
Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 6,610 delay minutes reported on AA 1177.
Cancellations run at 2.75%, against 1.81% nationally. That is roughly 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% 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 1,192 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 1177 is not only a DCA to DFW flight. It also flew DFW to DCA (304 flights, 84.1% 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.

What to do with this
Booking AA 1177
For a booking, the cancellation rate is the figure to plan around on AA 1177: 2.75% of its 364 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.
