An executive assistant’s guide to arranging a Chicago protective detail

If you are the executive assistant, chief of staff, or family-office lead behind a principal’s trip, whether to Chicago or anywhere else in the country or abroad, you already hold the most important input to a protective detail: the itinerary. The protection provider plans the advance work, the staffing, and the movements, but it plans them around what you send and when you send it. This guide covers the assistant’s side of that work: what to do at each stage, what to share first and what to hold back until a secure channel is agreed, how to brief the principal, and what to ask for once the trip is over.

What the detail itself involves, including arrival planning, multi-day staffing, and what to send before the first call, is covered on our executive protection page. For a read on the city itself, start with our straight answer on Chicago for visiting executives.

A planning timeline

The timeline below reflects good practice rather than fixed lead times. A short window is still workable; an experienced provider will tell you what it can advance in the time you have.

The same steps, set out as a checklist, are in our executive protection booking checklist.

What to send first, and what to exchange later

The first message does not need to be complete, and it should not contain everything. A useful rule is that the first contact carries the shape of the trip, and the specifics follow once you have spoken with the firm and agreed how documents will move.

Decide before the first call

• Who the provider deals with. One person on your side who can answer questions and relay decisions, plus a backup for the days you are unavailable.
• Who approves. Whether a budget holder, general counsel, or corporate security needs to sign off, and how long that usually takes.
• What the principal knows. Whether the principal has asked for protection, agreed to it, or is expecting you to handle it quietly. The answer changes the briefing.
• What already exists. A traveling security team, a corporate security function, a car service the principal prefers, or venue security at an event.

Exchange later, through the agreed channel

• Flight numbers or private aviation details, and exact arrival and departure times
• Hotel name and the name the reservation is held under
• The full itinerary with addresses, times, and host contacts
• Guest lists for private dinners or meetings, where relevant
• Names and mobile numbers of everyone in the traveling party
• Any health information the principal chooses to share that matters for the day, such as a serious allergy

Please keep detailed itineraries out of any website contact form, ours included. A brief outline is enough to start.

Briefing the principal

Principals who know what to expect tend to work comfortably with a detail. A one-page note, or five minutes before the trip, usually covers it:

• Who they will meet. The lead agent’s name, and where and how the principal will be met on arrival.
• What the agents will do. Walk ahead through entrances, check a room before the principal enters, wait nearby during meetings and meals rather than join them.
• How to change plans. Tell the lead agent directly, and the lead will tell you. A change mentioned only to the driver can leave the rest of the detail behind.
• What you need from them. Their preference on visibility, any stops they are likely to add (a run, a gym, a visit to a friend), and whether family members or guests will join.

It also helps to ask the principal one question before the trip: is there anything or anyone you would rather we knew about in advance? The answer sometimes shapes the plan more than the itinerary does.

Coordinating the hotel, venues, drivers, and staff

Much of the assistant’s value on a trip is introductions. The provider can do its own outreach, but an email from you connecting its point of contact to the right people saves time and establishes that the firm is acting for the principal.

• Hotel. Introduce the provider to the hotel’s security or front office manager. Ask the hotel what it allows for reservation names, arrival by a side or garage entrance, and room placement, and share the answers with the provider.
• Venues and hosts. For each meeting, dinner, or event, give the provider a named contact at the venue or the host’s office. Event organizers usually want to agree the arrival door, the green room, and how the principal moves through the room.
• Drivers. If you are using your own car service, connect the driver or dispatcher with the lead agent before arrival, and agree who decides routes and pickup points. If the provider is arranging vehicles, see what secure transportation involves.
• The principal’s other staff. A communications lead, a traveling chief of staff, family members’ assistants, or the principal’s own security team each need to know who the point of contact is. Agree one channel for the detail rather than adding agents to every group chat.

When plans change mid-trip

Itineraries change. A meeting runs long, a dinner is added, a flight is delayed. The assistant’s job is to keep the changes flowing through one path: you to the provider’s point of contact, and the point of contact to the agents. When you send a change, say what changed, the new time and address, and who is affected.

A stop that appears at short notice may not have been advanced. The lead may suggest a different entrance, a short delay, or an alternative location, and it is worth hearing that out before confirming with the host. Ask during scoping how the provider handles added hours, extended days, and cancellations, so a change on the day does not become a billing surprise later.

Information hygiene, without the paranoia

Most itinerary exposure is ordinary: a schedule forwarded one time too many, a calendar invite visible to a whole department, or a social post made while the principal is still in the room. A few habits handle most of it.

• Limit who gets the full itinerary. The provider’s lead needs the whole thing. Most other people need only their part: a host needs the arrival time at their venue, not the rest of the day.
• Keep details out of shared calendars and auto-replies. An out-of-office message that says where the principal is traveling is easy to forget and easy to forward.
• Post after, not during. If the principal or the team shares photos from the trip, posting after leaving a location gives away less than posting in real time.
• Use the channel you agreed. Send itinerary updates through the method set up with the provider, and avoid scattering versions across email, text, and messaging apps.
• Retire old versions. Mark each itinerary with a version number or date, and follow your organization’s retention practice once the trip is over.

None of this requires special software or secrecy for its own sake. It is the same care you would give a confidential deal calendar.

Comparing proposals

When you have more than one proposal, check first that they describe the same trip: the same days, hours, number of agents, advance work, and transportation. Beyond price, the questions that matter most to an assistant are practical. Who will be your point of contact? How are changes handled, and how are added hours billed? How will the itinerary be shared and stored? What will you receive after the trip? Our guides on how to choose an executive protection company and what drives the cost cover what to ask, red flags, and pricing structures in more detail.

What a post-trip debrief covers

A debrief can be a fifteen-minute call. It is most useful when it covers:

• What went to plan, and what changed and why
• Anything the detail noticed that is worth knowing before the next visit
• Notes on the hotel, venues, and routes: entrances that worked, contacts who were helpful
• Whether the itinerary reached anyone it should not have, and how to tighten distribution next time
• The principal’s feedback on visibility, comfort, and the agents
• Hours worked against the proposal, before the invoice is paid

Keep the notes in a trip file. The next visit then starts from what you learned rather than from a blank page.

Example (hypothetical)

A chief executive is coming to Chicago for two days: a private aviation arrival on Tuesday afternoon, a board meeting at a hotel in the West Loop, an investor dinner that evening, and a conference keynote on Wednesday morning before flying home.

The assistant contacts a provider when the board date is set, sending dates, the rough schedule, three travelers, and the fact that the keynote is publicly announced while the dinner is private. After a scoping call, two proposals come in; the assistant compares them on agents, hours, advance work, and how changes are billed, and chooses one about ten days out. The full itinerary goes to the provider’s point of contact through the channel they agreed. The assistant introduces that contact to the hotel’s security manager, the restaurant’s events coordinator, and the conference organizer, and sends the chief executive a short note naming the lead agent. On Tuesday the investor dinner moves back an hour; the assistant sends one message to the point of contact, who handles the rest. The following week, a short debrief notes that the conference loading dock worked better than the main entrance, and that goes into the trip file.

Common questions

How far ahead should an executive assistant arrange protection for a Chicago trip?

Start as soon as the dates are known, even if some are tentative. A first conversation needs only the shape of the trip. Detailed itineraries follow once a secure exchange is agreed, and advance work on the hotel, venues, and routes typically happens in the week or two before arrival. Shorter windows can work, with less time for advance work, so ask the provider what it can do properly in the time available.

What should I send a protection provider first?

Send the outline: dates and which are tentative, cities, the general shape of the schedule, the number of travelers, which items are public and which are private, and any known concerns. Hold flight numbers, hotel reservation names, full addresses, and guest lists until you have spoken with the firm and agreed a secure way to exchange them.

How should I brief the principal about the detail?

Keep it short: the lead agent’s name, how the principal will be met on arrival, what the agents will do during the day, and that schedule changes should go to the lead agent directly. Ask the principal about visibility preferences and any stops they are likely to add.

Can we use our own driver or car service with a protective detail?

Often, yes. Connect the driver or dispatcher with the lead agent before arrival and agree who decides routes and pickup points. If the provider is arranging vehicles and security drivers, that is scoped as part of the proposal.

What happens if the itinerary changes during the trip?

Send each change through one channel to the provider’s point of contact, with the new time, address, and who is affected. A stop added at short notice may not have been advanced, so the lead may suggest an alternative entrance, timing, or location. Ask during scoping how added hours and cancellations are billed.
