Additional security measures for international flights to the U.S.

In addition to standard security procedures, the U.S. Department of Homeland Security (DHS) requires additional security measures for all international flights to the U.S., which may result in extra screening for everyday items such as large electronics, powder, food, books and magazines. TSA has a full list of what is and isn’t allowed on their website.

Large electronics: Travelers with electronic devices larger than a standard smartphone should be prepared to remove these devices from their protective cases or outer packaging for inspection. If you h​ave a case that requires a screwdriver or other special tools to remove, we recommend doing so before arriving at the airport.

Powder-based substances: We recommend all customers place any items that resemble powder in their checked baggage. Some travelers with powder-based substances in their carry-on bags and personal items greater than what would fit in a standard soda can (12 fluid ounces or 350 milliliters) may be subject to additional security measures put in place by the DHS.

For those selected for additional security measures, powder substances in excess of this amount won’t be allowed in the cabin of the aircraft. Examples of powder include ground coffee and tea, flour, sugar and spices. There are some exemptions, including baby formula, medically necessary powder and human remains.

Please note that some foreign governments who perform this screening at the central checkpoint may follow more strict measures, including confiscating and disposing of powder-based substances in excess of permitted quantities.

Arrival times: The Transportation Security Administration (TSA) recommends arriving at the airport at least three hours before your international flight to allow time for the additional security measures. Please note the airport check-in hours first.

For more information, please visit the DHS website. You may also contact @AskTSA via Twitter or Facebook Messenger with specific questions or visit TSA customer service.

Cuba travel policy changes

As of June 16, 2017, individual people-to-people travel to Cuba for customers who are subject to U.S. jurisdictions are no longer allowed. All customers booking travel on United to or from Cuba must certify their eligibility under one of the authorized categories provided. Please visit the U.S. Department of the Treasury’s Cuba travel page to learn more about the authorized categories for U.S. citizens to travel to Cuba.

Additional security screenings at Panamá City and El Salvador airports

Tocumen International Airport (PTY) in Panamá City, Panama, and El Salvador International Airport (SAL) have additional security screenings in place, so you’ll need to go through two checkpoints — one to enter the terminal and one at your gate area. You won’t be able to bring liquids over 3 ounces through either checkpoint, and you’ll need to remove laptop and tablet covers at both checkpoints. We recommend getting to the airport early so you have plenty of time to get through security.

Traveling on flights precleared by U.S. Customs and Border Protection

If you’re traveling to the U.S. from one of the international airports listed below, we recommend you arrive at the airport three hours before your scheduled departure time. Flights from these airports are precleared by U.S. Customs and Border Protection, so please allow extra time to complete additional border security screening processes before you depart. When you arrive in the U.S., you’ll arrive at a domestic terminal.

We operate flights precleared by U.S. CBP before departure from the following international airports: Aruba (AUA), Bermuda (BDA), Dublin (DUB), Freeport (FPO), Nassau (NAS), Shannon (SNN), Edmonton (YEG), Halifax (YHZ), Ottawa (YOW), Montreal (YUL), Vancouver (YVR), Winnipeg (YWG), Calgary (YYC) and Toronto Pearson (YYZ).

TSA and other security updates

Important information about U.S. IDs

If your state is not compliant and has not filed an extension, you’ll need to use an alternative form of identification, such as a passport, when flying within the U.S.​​​​​​​​​​​​​​​​​

Some flights may also be delayed. Travelers are encouraged to use public transportation and check flight statuses before heading to the airport.
