New CDC Flight Rule: What Travelers Must Sign Before Nov. 3

Starting at 11:59 p.m. Eastern time on November 3, everyone boarding a flight to the United States from another country must sign a statement saying they have not been in the Democratic Republic of the Congo (DRC) in the 21 days before boarding. The rule, published by the Centers for Disease Control and Prevention (CDC) on October 30, applies to passengers and crew alike, and it runs through December 18 unless the CDC changes or ends it sooner.

What we know / What we don’t know

What we know:

• The CDC issued an amended order on October 28, 2026, and published it in the Federal Register on October 30, 2026.
• The order takes effect at 11:59 p.m. Eastern Standard Time on November 3, 2026, for flights departing at or after that time, and it remains in effect through 11:59 p.m. EST on December 18, 2026.
• It covers any person boarding an aircraft destined for the United States from a foreign country, unless the person is covered by an exemption.
• The signed statement, called an attestation, must confirm the person has not been present in the Democratic Republic of the Congo during the 21 days before boarding.
• The National Business Aviation Association (NBAA), in its October 30 update, says the requirement covers passengers and crew members, including crew traveling in a non-operating capacity, and applies to commercial flights, general aviation, and business aircraft.
• The attestation can be digital or paper, and the aircraft operator must keep it for at least 42 days after the flight arrives in the United States, according to the NBAA summary of the CDC order.
• A traveler who has been in the DRC in the past 21 days generally cannot board a U.S.-bound flight until day 22 after leaving the country, unless a government exemption applies.
• A stop in a DRC airport counts as being present in the DRC, even if the traveler stayed on the airplane or did not leave the airport, according to the NBAA summary and other reports of the order.
• U.S. citizens and U.S. nationals are not exempt simply because of their citizenship, and the rule applies no matter which foreign country the flight departs from.
• Airline groups, including Airlines for America and the International Air Transport Association, have asked the CDC to reconsider the timetable, saying carriers have little time to change their procedures.

What we don’t know:

• The CDC order summary does not list every exemption in plain language for ordinary travelers. Travelers who think an exemption might apply to them should check the official CDC guidance or their airline before traveling, rather than assuming they qualify.
• The CDC has not said whether the order will be extended past December 18. The notice says it may be amended or rescinded before that date at the discretion of the Secretary of Health and Human Services or a designee.
• This article does not give a total case count for the Ebola outbreak in the DRC, because counts change quickly and different sources report different totals. The rule itself, not a single case number, is what travelers need to act on.

Key facts

What the rule requires

The rule is simple on its face, and that is the point. Before you board a flight to the United States, you must sign a short statement. That statement says you have not been in the Democratic Republic of the Congo in the 21 days before your flight.

The Federal Register notice describes the order in direct terms. It prohibits boarding any person who is not otherwise subject to an exemption on any aircraft destined for the United States from a foreign country unless that person presents a signed attestation confirming they have not been present in the DRC during the 21 days prior to boarding.

In practice, most travelers will see this as one more step at check-in or at the gate. The CDC allows a digital form, a paper form, or an electronic confirmation built into an airline’s check-in system, according to reports of the order. You do not need to print a form in advance unless your airline tells you to, but it is wise to check your airline’s instructions before you head to the airport, because airlines are still updating their own procedures.

If you cannot or do not complete the statement, you may be denied boarding, unless an exemption applies to you. That is the practical consequence travelers should understand before November 3. It is not a test, a vaccine check, or a quarantine order. It is a signed declaration about where you have been.

Who it covers

This is the part that surprised many travelers when the amended order was published. The original order, issued on October 22, covered airline passengers. The amended order, issued on October 28, makes clear that crew members are covered too.

The National Business Aviation Association’s October 30 update puts it plainly: the CDC order prohibits air carriers and aircraft operators from boarding any person, including crew members, departing any foreign country for the United States unless the person provides a digital or paper attestation. That includes pilots, cabin crew, people operating cargo aircraft, and crew members traveling as passengers, sometimes called deadheading crew.

It also covers more than big commercial airlines. The NBAA update says the requirement applies to commercial flights, general aviation, and business aircraft. Private and business-aircraft operators must be ready to collect the same statements, and the NBAA warned its members to prepare alongside commercial airlines.

Citizenship does not change the rule. U.S. citizens and U.S. nationals traveling home from abroad must sign the same statement. The NBAA update says travelers, including U.S. citizens and U.S. nationals, who have been in the DRC within 21 days of their flight will not be allowed to board flights with U.S. destinations. The rule also applies no matter which country your flight starts in. A flight from London, Paris, Dubai, or Toronto is covered in the same way as a flight from a country closer to the DRC, because the question is where you have been, not where you are boarding.

What counts as being in the DRC

This is the detail most likely to catch a traveler by surprise. Being present in the DRC does not only mean visiting the country and staying there. It includes passing through.

According to the NBAA summary of the CDC order, all U.S. citizens and U.S. nationals who have been in the DRC should plan to remain outside the DRC for 21 days before entering the United States. That includes passengers with an intermediate stop in the DRC or on multi-stop trips through the DRC, regardless of whether they got off the airplane or stayed on board.

In other words, a layover in a DRC airport counts, even if you never left the airport. Flying over the country without landing does not, by itself, count as being present there, according to reports of the published rules. If your trip includes any stop in the DRC in the past 21 days, the safe move is to check with your airline before you travel and to plan for the 21-day wait, unless a government exemption applies to your case.

The 21-day window is tied to Ebola’s incubation period, the time between exposure and symptoms. The CDC counts the day you leave the DRC as day zero, and the first full day outside the country as day one. That means a traveler who left the DRC on a given day would generally be able to board a U.S.-bound flight starting on day 22, unless an exemption applies.

When it starts, and when it ends

The dates matter, because the rule does not start the day it was published. It starts a few days later, and it has a set end date.

The amended order was issued on October 28 and published in the Federal Register on October 30. It takes effect at 11:59 p.m. Eastern Standard Time on November 3, 2026. It applies to flights departing a foreign country for the United States at or after that time. If your flight leaves before that moment, the new attestation rule does not apply to that flight under this order, though earlier CDC measures may still apply.

The order runs through 11:59 p.m. EST on December 18, 2026, unless the CDC amends or ends it sooner. That end date is worth noting for anyone planning December travel. A trip in early December falls inside the rule. A trip after December 18 may not, unless the CDC extends the order. Travelers should check the latest CDC guidance close to their travel date, rather than assuming the December 18 date will hold.

The timing also lands just after the clocks change in the United States. Daylight saving time ends on November 1, and the country returns to standard time — a shift that already affects flight times and connections. Our guide to daylight saving time ending and clocks falling back explains that change, and it is one more reason to double-check departure times in local time when you travel in the first week of November.

Why the CDC issued the order

The CDC issued the order in response to an Ebola outbreak in the Democratic Republic of the Congo caused by Bundibugyo virus. The goal, as the CDC describes it, is to reduce the chance that the virus is brought into the United States by air travel.

The CDC’s October 30 outbreak assessment, as reported by secondary coverage of the order, says no U.S. Ebola cases have been confirmed in connection with this outbreak and that the overall risk to the American public and travelers remains low. The attestation is a prevention step, not a response to cases already found in the United States. It is meant to catch the risk before boarding, by asking every traveler to confirm recent travel history in a signed form that airlines must keep.

The order sits alongside other CDC measures that remain in place. For example, the NBAA update notes that U.S. citizens and U.S. nationals who have been present in Uganda or South Sudan, but not in the DRC, within 21 days of arrival in the United States must only enter through designated airports for enhanced screening. Those designated arrival airports are Washington Dulles International Airport, Hartsfield-Jackson Atlanta International Airport, and John F. Kennedy International Airport. That rule is separate from the new attestation, but travelers with recent travel in that region should know both rules may apply to them.

What airlines are saying

Airlines and aviation groups have not disputed the health goal, but they have asked for more time. According to coverage of the amended order, Airlines for America and the International Air Transport Association have separately urged the CDC to reconsider the implementation timetable, saying carriers have limited time to adapt their procedures before the measure takes effect.

That pushback matters for travelers for a practical reason. Even when a rule is clear on paper, airlines need time to add a checkbox to check-in, train gate staff, and prepare paper forms for airports where digital systems are not ready. If your airline’s system looks different from what you expected on November 3 or 4, that is likely why. The rule itself has not changed unless the CDC announces a change. Check your airline’s travel alerts and your booking confirmation for the latest instructions for your specific flight.

What travelers should do before November 3

If you are flying to the United States from abroad on or after November 3, take these simple steps. First, check your travel history for the past 21 days. Did you visit, pass through, or stop in the Democratic Republic of the Congo, including a layover where you stayed on the plane? If the answer is no, you will sign a statement saying so. If the answer is yes, do not assume you can board. Contact your airline and check the official CDC guidance before you travel, and plan around the 21-day rule unless a government exemption applies to you.

Second, check your airline’s instructions. Look for a travel alert, a check-in prompt, or a form link in your booking. Some airlines will collect the statement digitally during online check-in. Others may hand you a paper form at the airport. Either form is allowed under the order.

Third, keep your travel documents in order and allow extra time at the airport in the first days of the rule. New check-in steps can slow lines, especially at busy international airports. Arriving early is a simple way to avoid missing a flight over paperwork.

Fourth, if you are traveling with children or on behalf of someone else, check whether you need to sign for them. The CDC attestation form asks for the traveler’s name, signature, and date, or information identifying an authorized representative signing for someone else, according to secondary coverage of the form. When in doubt, ask your airline who should sign for a child or a traveler who cannot sign for themselves.

Finally, keep an eye on updates. The CDC can amend or end the order before December 18. If you booked a flight for late November or December, recheck the guidance a few days before you fly. Rules that affect travel, like the new Airbnb checkout-chores policy that changed what hosts can ask guests to do, can shift quickly, and the official source is always the safest place to confirm the current version.

What this rule is not

It helps to be clear about what this rule does not do. It does not ban all travel to the United States. It does not require a test, a vaccine, or a quarantine for every international traveler. It does not apply to domestic flights inside the United States. And it does not change the advice for travelers who have not been in the DRC at all, beyond asking them to sign the statement.

For travelers thinking about health preparations more broadly, our guide on the flu vaccine for adults over 50 and what is new in 2026 covers a separate, routine health step that many travelers consider before winter trips. That guide is about flu vaccination, not Ebola, and it does not replace the CDC attestation or any airline instruction for your flight.

The bottom line is straightforward. If you are flying to the United States from another country on or after November 3, expect to sign a short statement that you have not been in the Democratic Republic of the Congo in the past 21 days. If you have been there, or even stopped there, plan for the wait and check with your airline first. The rule is in place through December 18, and the signed form is now part of boarding — not an optional extra.
