I remember back in the 80's that the old World Airways used to operate out of the Imperial Terminal at LAX rather than the other terminals. It wasn't very convenient to the other terminals for connections sake, and I'm not sure of it offered the same amenities present a the others.
Why did World Airways opt to use the Imperial Terminal? Did any other carriers use it at any other time? Also, is it being used for scheduled ops now? If not what is it used for?
