MEM across all twelve months

Against the year

April next to MEM's other months

Against MEM's own year, April ran 2 points better than the twelve-month rate of 80.0%, which makes it number four of twelve months, best first. Cancellations were unusually low for MEM in April, at 0.98% against 2.27% across the year. Either side of it, March ran 77.1% on time and May 79.8%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave MEM in April

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 10 points between the best and worst carrier.

5am–8am704 flights91.5%
8am–11am373 flights86.6%
11am–2pm341 flights81.4%
2pm–5pm297 flights67.1%
5pm–8pm377 flights74.7%
8pm–5am54 flights68.5%

Scale runs 60% to 95%.

Book the early departure. Flights leaving between 5am–8am arrive on time 91.5% of the time, against 67.1% for the afternoon window. That is 24 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 704 flights scheduled in it.

Across the week, Wednesday is the strongest day at 84.5% on time and Tuesday the weakest at 79.5%, a spread of 5 points.

Carrier by carrier

Which airlines ran best at MEM in April

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 90.7% of the time; Southwest Airlines manages 81.0%. Sample sizes sit next to every figure, because a two-point gap across 379 flights means less than a ten-point one.

Delta leads Southwest by 10 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held MEM up in April

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 32,000 reported delay minutes.

Late-arriving aircraft
38%
Carrier
37%
National Airspace System
15%
Extreme weather
10%

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 32,000 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 31,669 reported delay minutes.

Cancellations sit at 0.98% against a national 0.90%, which is ordinary. Diversions add another 0.19%.

6.9% of arrivals land an hour or more late, close to the national 6.4%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
