MANILA - Philippine Airlines will implement additional security measures on all its flights bound for points in the United States and Canada, in response to an emergency advisory of the U.S. Department of Homeland Security.

Effective immediately, all North America-bound PAL passengers are advised that:

* No liquids or gels are permitted on board the aircraft as carry-on items. These include beverages, shampoo, lotions, creams, toothpaste, hair gel and other items of similar consistency.

* Exceptions are allowed only in the following cases:

a) Baby formula, breast milk or juice if a baby or small child is traveling
b) Prescription medicine with a name that matches the passenger's ticket
c) Insulin and other essential non-prescription medicines

* PAL and airport security will thoroughly search passengers' carry-on baggage as well as their persons to ensure compliance. Any item listed above will be confiscated. To avoid this, passengers are advised to include such articles in their checked luggage.

* Passengers who refuse to be searched will be denied boarding.

* Passengers are strongly advised to travel light, especially concerning their carry-on baggage, in order to expedite the screening process.

These measures are on top of ongoing security procedures on all North America-bound PAL flights, such as the removal and screening of footwear, and the exclusion of pointed, bladed and flammable items onboard.

Covered by this advisory are PAL flights from Manila bound for Los Angeles, San Francisco, Las Vegas (via Vancouver), Honolulu and Guam.
