Departure window

The best time of day to leave MEM in June

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 43 points, against 20 points between the best and worst carrier.

  • 5am–8am681 flights92.2%
  • 8am–11am363 flights82.5%
  • 11am–2pm299 flights73.5%
  • 2pm–5pm406 flights65.2%
  • 5pm–8pm425 flights60.7%
  • 8pm–5am47 flights48.9%

Scale runs 40% to 100%.

The 8pm–5am window is where this operation falls apart: 48.9% on time, against 92.2% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 681 flights scheduled in it.

Across the week, Tuesday is the strongest day at 86.4% on time and Sunday the weakest at 64.8%, a spread of 22 points.

Which airlines ran best at MEM in June

Delay causes

What held MEM up in June

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 45,000 reported delay minutes.

  • Late-arriving aircraft
    39%
  • Carrier
    28%
  • National Airspace System
    19%
  • Extreme weather
    14%

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 comparison with the other months below is the more useful view of the risk. The national share is 7%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 44,849 reported delay minutes.

Cancellations sit at 2.34% against a national 1.65%, which is ordinary. Diversions add another 0.50%.

9.7% of arrivals land a full hour or more behind schedule, against 9.7% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

What to do with this

Flying from MEM in June

For a June trip through MEM: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 92.2% on time, and with 9.7% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
