SAN DIEGO -  

Volunteers and staff at the San Diego International Airport will continue their efforts Sunday to ease holiday traveling stress by offering ticketed passengers free gift wrapping, according to the San Diego County Regional Airport Authority.

Sunday is the last day the gift wrapping stations, which got under way Friday, were scheduled. Volunteer airport ambassadors and airport authority employees will wrap gifts from 6 a.m. to 6 p.m.

Airport officials said wrapped presents should not be taken on airplanes, because security officers might have to unwrap them. Gifts that were not shipped ahead of time should be wrapped after passing through security, officials said.

Officials said the rules for liquids in carry-ons would apply to holiday gifts, even those purchased at the airport before the security checkpoint.

Items like perfume, lotion, wine or alcohol and gift baskets with salsa or jam must be 3 ounces or less and placed in a clear, quart-sized plastic bag if transported in a carry-on bag.

Items purchased after the security checkpoint have been pre-screened and could be taken on flights, officials said.
