There is lots to do right by the terminal if you arrive early. Drop your bags off, park, then hit up a place to sight see or grab NOLA lunch, then board when it is less crowded. We checked in early. Wound up waiting 3 hours to get onboard. Luckily we were at the front of the line and got through quickly. We sat for about 2.5 hours. Others wound up standing in line, wall to wall people, for 2.5 hours.
