We flew into Long Beach (on Jet Blue from FLL) the morning of the cruise. It was an easy short ride to the port. We spent a few days post cruise in LA but I remember we were easily off the ship by 9:30am. We took the supershuttle to Beverly Hills and there was another couple in our van going to LAX for a noon flight. Could be tight, but the 2:30 JetBlue sounds perfect for you...should be no stress with that time frame!
