ACK security, common questions

How early should I get to ACK?

For a domestic flight out of Nantucket, plan to be inside the terminal about an hour before departure, and about an hour for an international one. That covers a 5 to 15 minute checkpoint queue at the Saturday peak plus the walk to the gate. Outside the peak you can safely trim it; the calculator above works it out from your actual departure time.

What is the busiest time at ACK security?

Saturday around 3 pm, when 2 departures' worth of passengers are converging on the checkpoint at once. The calmest hour with real traffic is Sunday at 8 am, at roughly 4 minutes.

Is TSA PreCheck worth it at ACK?

At the Saturday peak it turns a 5 to 15 minute queue into something closer to 3 minutes. Over a five year membership that is worth it if you fly more than about three round trips a year through an airport this busy. The trusted traveler calculator prices it against your own flying.

When does security open at ACK?

Nantucket Memorial Airport does not publish checkpoint opening hours in any national feed, so we will not invent them. What the schedule does show is that the first departures leave around 9 am, and checkpoints generally open about two hours before the first flight of the day.

How long is security at Nantucket?

At the Saturday peak around 3 pm, the standard lane at ACK typically runs 5 to 15 minutes. Away from the peak it settles to roughly 4 minutes. These are modeled from the airport's own departure schedule, so they move hour by hour, which is what the chart on this page shows.

How much time does PreCheck save at ACK?

At the busy Saturday peak, PreCheck turns the standard 5 to 15 minute wait into about 3 minutes, a saving of roughly 7 minutes when it matters most. Off-peak the two lanes are much closer, because a short line is short in either one.

Tips for ACK, from the data

  • Fly between 7 to 11 AM if you can. That window sits between the two daily rushes, when the checkpoint is at its calmest.
  • The 2 pm hour is the single busiest today, at about 8 minutes in the standard lane.
  • JetBlue runs 49% of departures here, so its checkpoints and gates carry the most traffic. Which airline you fly is what decides your terminal.
