We are cruising from New Orleans this December and On return have a late flight. We have a lot of time to kill. Is there a place to store our bags until we leave? Is there an excursion we can go on that would take us to the airport after?

There is a place at the cruise terminal where you can store your luggage and they can also set you up with transportation.

Yes on storage and if nothing else works just UBER to a nearby place.

Look up local tours and schedule it around the time you come. Far as getting to the airport Lyft and Uber are very high in presence around here.

Yes
