The U.S Transportation Security Administration (TSA) has implemented the following changes to airport screening procedures. These procedures will remain in place as circumstances warrant.
PASSENGERS MAY NOT HAVE LIQUIDS, GELS, OR AEROSOLS OF ANY SIZE AT THE SCREENING CHECKPOINT OR IN THE CABIN OF THE AIRCRAFT.
These items include beverages, shampoo, suntan lotion, creams, toothpaste, hair gel, hair spray, liquid cosmetics and other items of similar consistency. Such items may be transported in checked baggage.
Passengers may have:
Baby formula/milk and baby food in small containers if a baby or small child is traveling.
Prescription medicine with a name that matches the passenger’s ticket.
Essential other non-prescription medicines not to exceed 4 oz. (120ml) per container.
Liquids or gels for diabetic passengers who indicate a need for such items to address their medical condition. Quantities are limited to no greater than 8 oz. (240ml) per container. Syringes and pumps are acceptable.
Solid cosmetics and personal hygiene items such as lipstick in a tube, solid deodorant, lip balm and similar solids.
Please note that all of these approved items must be presented for inspection at the security checkpoint. All types of footwear must also be screened by x-ray. Customers traveling from the U.K. to the U.S. should expect even more extensive screening processes.
Any beverages purchased in the boarding area (beyond the security checkpoint) must be consumed before boarding, as they will not be permitted on board the aircraft.
Duty free liquid purchases are allowed on a flight if they are delivered to a customer as the customer boards and are terminating at the destination of the flight. Connecting customers cannot take duty free liquid purchases on the connection segment, and it will be confiscated by the TSA. This applies to online connections as well as interline.
Please arrive 60 minutes prior to your scheduled departure for U.S. domestic flights if you are not checking bags, and 90 minutes before your flight if you are checking bags. For international flights, please arrive 2 hours prior to scheduled departure. View current check-in arrival times for your airport.
