Aeroméxico Reminds Passengers of New US Sworn Declaration Requirement Over Ebola Concerns

Mexico City — Travelers flying to the United States must now sign a sworn declaration stating they have not been in the Democratic Republic of Congo during the previous 21 days, and Aeroméxico is reminding passengers that the paperwork is mandatory before boarding.

The rule took effect Wednesday, November 4, 2026, and applies to every passenger on an international flight arriving in the United States, regardless of nationality. Aeroméxico posted the notice on its social media accounts and shared a link so travelers can sign the document ahead of their trip. Volaris has also alerted its passengers to the requirement.

The measure was issued by the US Centers for Disease Control and Prevention (CDC) to reduce the risk of Ebola spreading through air travel.

Who Must Sign the Declaration

The requirement covers all passengers arriving on international flights, including:

• US citizens
• US permanent residents
• Foreign nationals, including Mexican travelers
• Passengers connecting in the United States before continuing to another destination
• People traveling on commercial, private or general aviation flights

Each passenger must submit a separate declaration. For travelers under 18, a parent, guardian or another authorized adult may sign on their behalf.

How to Complete the Form

1. Check with your airline on how it will collect the health declaration.
2. Access the document. Aeroméxico has posted a link for passengers to sign it.
3. Fill in accurate information about where you have traveled during the past 21 days.
4. Sign the form before boarding.
5. Hand it in when the airline requests it, either at check-in or at the gate.

The form may be submitted on paper or digitally, depending on each carrier’s procedure. The CDC has also published an official PDF form that airlines can use.

What Counts as Having Been in Congo

Under the CDC definition, time in the Democratic Republic of Congo is not limited to a tourist or business visit. A traveler is considered to have been in the country if they entered by air, land or sea, passed through it, or made a connection at one of its airports — even without leaving the aircraft or the terminal. Overflying the country without landing does not count.

Passengers who fail to complete and submit the declaration will not be allowed to board flights to the United States unless they hold an exception authorized by the US government.

Knowingly providing false or misleading information can carry legal consequences, including fines and prison time under US federal law.

Rule Runs Through December 18

The requirement is scheduled to remain in force until December 18, 2026, unless the CDC decides to modify or cancel it earlier.

Travelers with upcoming flights to the United States should review their airline’s instructions and make sure they have the declaration ready before heading to the gate.
