I just checked my A318 that works at me. Often MIA means you not have downloaded the right planes. WE have more then 1 A318. Also sometimes you have MIA and UFO Planes if the steam download was broken. Then unsubscribe them , and subscribe them again (sometimes2-x3) Then it should work. I also have got a A318 Problem at some airlines , because the game adds a -1 steam id automaticly in the config , then game wants that broken A318 from a other modder. You just need to go to the config of the airline , and remove the -1 at needed planes steam ids . (that only the user can fix, sorry ) (game/steam bug) If you have more problems come to SA Discord , there we can help better. (link is in the steam discussion) I always try to fix my mods. So let me know if you have any problem, but then i need the name of airline/aircraft+Steam id.

Hey, these mods aren't working properly. The A318 Aircraft config file says it's missing in mod downloads and a lot of the airlines are using a small plane and planes say MIA for the aircraft. The aircraft arrive and pick people up, but the image of the aircraft doesn't work.

Also the other Southwest liverys are online (Desert Gold as Southwest OL. and Canyon Blue as Southwest.)
