Consistent with these higher threat levels, the Transportation Security Administration is implementing changes to airport screening procedures to include:
* No liquids or gels of any kind will be permitted in carry-on baggage. Items must be in checked baggage.
Exception: baby formula, breast milk, or juice if a baby or small child is traveling; prescription medicine, insulin and essential other non-prescription medicines.
Travelers should also anticipate additional security measures within the airport and at screening checkpoints.
