The Luebeck airport has about 2 - 4 flights per day... all international.
If you want to fly Luebeck-Wuppertal, you have to do HAM-DUS or HAM-CGN, but both will take longer in total compared with the train Luebeck-Wuppertal.
There are a few direct trains with a travel time of ~4.5h. You can try to search at
