Away tickets

Why are the away matches going on sale so late. I mean it’s just over 2 weeks before Huddersfield and no information has been stated. I know the supporters club are selling to a certain criteria but it all seems so late. Is it perhaps because it’s the start of the season but matches will go on sale a month in advance once we get into September. On the plus side at least 2 weeks in advance people tend to know what they are doing for example work shift patterns and family plans etc.
