Are there plans for more garages? I quit flying out of MSY due to no parking. Never seen another airport where parking is full, much less consistently full.
Unfortunately, no. Total screw-up in the planning process. Unless you fly out on Tuesday mornings, the lots are generally full. Thursday-Sunday its basically shut out. (Unless you want to park in the old garage by the old terminal and take a 15 minute bus ride - no thanks).
I did discover that you can reserve a spot on their website and then park there even if it shows 'full' but I usually just uber at this point.
