We had a 6pm flight out of Long Beach on a Monday in May. We caught the 3:45 shuttle from the park to the candy cane inn. We got right in to our rental car and hit the road. We stopped for gas before getting to the airport. We returned the car, checked in at the airport and were thru security by 5. I would allow more time then that if using a shuttle. Actually most shuttle companies will tell you what time they'll be there to get you because they are more then likely going to be picking up other passengers before dropping off at the airport. A taxi would be a more direct, time saving way to get there.
