Not all planes have 3 classes. Some have 6. It's all pretty arbitrary, I don't think it's actually set in stone anywhere what "class" means. Like I've been on flights with value economy, economy, economy plus, economy premium, business, first, first (premier? Or something). I've also been on flights that were "general," but if you paid 44$ extra you get a giant padded seat easily as big as or bigger than some first class seats I've seen.
