The recommended arrival time to Louis Armstrong New Orleans International Airport before a domestic flight is at least 2 hours before your scheduled departure time, and 3 hours before an international flight. This allows for enough time to check-in, clear security, and make it to your gate on time. However, arrival times can vary depending on the individual traveler’s needs and circumstances, such as if they are traveling with young children, have a lot of luggage, or require special assistance. When it comes to New Orleans airport parking, there must be some additional time included, if your car is not parked directly at terminals. This applies for Economy parking or off-site options, because shuttles need to be taken.
