currently there is no way to remove deleted airline mods from the game. It will not hurt anything to have them there

Thank you - The only real annoyance with this is that the "missing mods" warning pops up every time I save or load a game. But glad to hear it won't hurt anything.

The missing mods warning I think is only for object and script mods, but not a hundred percent sure. The missing mods can come up for some issues. duplicate textures in mod folder to mods used in save missing. To be sure you can look thru your playerlog to find the errors

the log on windows is located:
%userprofile%\AppData\LocalLow\LVGameDev LLC\SimAirport\Player.log

for other os there is a pinned message on the edge discussion board for log path

Hi , the missing mods warning comes also for aircrafts , but you can try to delete the airline from your workshop foulder , at steam/steamapps/workshop/content/598330 ,(and you also must unsubscribe them) but you need the Steam ID to find it. (The airline steam ID , that you find , in the sa mods editor , just open that foulder ,there you find it (also in the config all down)) if you delete this mods , it sometimes helps. (but make sure , that you deleted all flights of that airlines.
You use very old mods , there many not works 100% . Try some of mine , i always update them.
