We are flying Continental with carryons only because it is a short trip. Each of the 4 of us have one wheeled carryon suitcase (meets measurements and weight) and one "personal bag". We would like to bring our laptop by putting it in a sleeve and then into one of the personal bags. Is this allowed or does the laptop count as a personal item in and of itself? I know they sometimes ask them to be screened separately which is not a problem, but don't want to be over my baggage limit because of this.
