Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1940, check with American Airlines.

AA 1940 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 2.4 hours. That rests on 288 flights, with a median arrival 14 minutes early.

Set against the rest of the country, AA 1940's record is 12 points better than the US average of 77.6%. That gap is worth roughly 115 fewer late arrivals for every thousand flights.

These figures cover 288 flights between July 2025 and June 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.

Schedule

When AA 1940 flies

AA 1940 flies MEM to DFW without a single fixed slot. Its most common scheduled departure was 05:38, used on 54 of 288 flights, with 05:15 (46 flights) and 05:40 (44 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 05:1546 flights16.0%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 05:38 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 1940 runs level with that at 89.1%. 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 1940 quarter by quarter

Quarter by quarter AA 1940 held fairly steady: 84.9% in Jul–Sep 2025, 88.9% in Oct–Dec 2025, 92.9% in Jan–Mar 2026 and 87.2% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AA 1940 did best on Tuesday at 95.0% on time and worst on Saturday at 82.1%. Each day rests on about 41 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 1940 runs late

One category carries most of the weight here. Carrier accounts for 70% of the 4,334 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.

  • Carrier
    70%
  • National Airspace System
    15%
  • Extreme weather
    10%
  • Late-arriving aircraft
    5%

The largest share of delay minutes, 70%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,041 of the 4,334 delay minutes reported here. The split is drawn from 4,334 delay minutes reported on AA 1940.

Cancellations run at 4.51%, against 1.81% nationally. That is roughly one flight in twenty 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

6.2% 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 about 2.4 hours, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including DFW to SJC (60), but none flew often enough under AA 1940 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MEM to DFW only.

One caution: this is a thin sample. 288 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 1940

For a booking, the cancellation rate is the figure to plan around on AA 1940: 4.51% of its 288 scheduled flights did not operate. A late arrival costs about 2.4 hours, but a cancellation costs the day, so leave a later option open.
