Additional security measures for international flights to the U.S.
If you are flying from any of the last-point-of-departure airports into the U.S., you may experience a more extensive screening process and should prepare for additional screening of your property and personal electronic devices. We recommend arriving early to the airport to allow enough time for the screening process. Please know, there are no changes to items allowed in carry-on and checked baggage.
For your convenience, we encourage you to place powder-like substances over 12 oz. / 350 mL in your checked bags. Powders in carry-on baggage may require secondary screening, and powders that cannot be resolved by security officials will be prohibited from the cabin of the aircraft effective June 30, 2018.
Check with your airline if you have questions about your flight to the U.S.
