Waited 90 minutes for a rental car & there were no flights to New York after 11:30 AM on a Monday. Seemed weird for a major city. Go to Baton Rouge if you need more flexibility.
Terminals are NOT connected. Be sure you are at correct security checkpoint for your gate. DON'T be sneaky and go to different checkpoint to avoid long lines. Security lines actually move very fast.
The southwest terminal is nothing short of horrendous. They r doing construction on it and there are no places to eat that are full service and there is limited seating at the gates.
Louis Armstrong New Orleans International Airport (MSY) is the gateway to one of the most exciting cities in the world – New Orleans, legendary for its history, food and good times.
