Yeah, I definitely don't think it starts out as a carship. Most of the time it looks like a regular car in the trailers, in that final scene it's all wide and bulgy before the wings even start folding out. I expect it to be a relatively late game thing as per most FF games; just something to help with all the backtracking and optional exploration.
