Coping with tough security at Sea-Tac

If you're flying out of Sea-Tac Airport today, be ready for extremely tight security and lineups.

Check with your airline before you leave for Sea-Tac; flights to Britain in particular may be canceled or late.

While British Airways is attempting to operate its long-haul flights, including those between Seattle and London; the airline has canceled all of its short flights to and from Heathrow within Britain and Europe. Some London Gatwick flights also are canceled. (American Airlines has already canceled some of its flights to Britain from the East Coast.)

• There's information on the new security alert and rules at the Transportation Security Administration Web site, www.tsa.gov .

Here's a summary of the new restrictions at Sea-Tac, for all flights:

• Travelers can take carry-on luggage, but all liquids, gels or creams are forbidden. That includes beverages, shampoos, perfume, lotions, creams and toothpaste. They can't be carried through a security checkpoint or onto an aircraft, although they can be packed in checked luggage.

• Beverages bought at the airport must be consumed before boarding a plane. However, travelers may bring baby formula, breast milk and juice for a baby or small child. They will be inspected by security staff.

• Prescription medicine will be allowed in carry-on luggage if the name on the prescription bottle matches the passenger's ticket. Insulin also will be allowed.

• The new procedures are making long lines at security, so get to the airport two hours before departure.
