These figures cover 268 flights between September 2025 and August 2026. The median arrival is 14 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.

Across the year
AA 1108 quarter by quarter
AA 1108 did not run the same all year. Its best quarter was Jul–Sep 2026 at 94.3% on time and its weakest Jan–Mar 2026 at 79.7%, a swing of 15 points on roughly 67 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.

- Apr–Jun 202691 flights89.9%

Share of 260 completed flights by arrival against schedule.
A late pushback is often recovered here: of 25 departures that left 15 minutes late or more, 9 still arrived on time. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DFW.
The worst days
Worst days for AA 1108
The latest arrival of the period was on 6 March 2026, 3 hours 43 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across March, November and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 3 hours 43 minutes | Late-arriving aircraft |
| 29 November 2025 | 2 hours 54 minutes | Carrier |

Delay causes
Why AA 1108 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 2,042 reported delay minutes.
- 42%National Airspace System
- 29%Carrier
- 25%Late-arriving aircraft
- 4%Extreme weather
42% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 855 minutes out of 2,042, against a national NAS share of 21%. The split is drawn from 2,042 delay minutes reported on AA 1108.
Cancellations sit at 2.24% against a national 1.89%, which is ordinary. Diversions add another 0.75%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.6% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 986 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 seven other city pairs in the data, including DFW to SJC (33), DCA to CLT (27) and CLT to BNA (27), but none flew often enough under AA 1108 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to DFW only.
One caution: this is a thin sample. 268 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 1108
