On our last trip, we encountered clear sailing all the way to LAX and made our way to check-in about five hours early. We joined a long line at the counter, eventually creeping to the head. Too early: The agent would not let us check in nor would he accept our bags. We found one restaurant on this side of the security gate and enjoyed a meal while counting the time until we could line up again.
