While this problem is not unique to Spirit, it is certainly annoying. My brother bought tickets on us for early October only to have them completely cancel that route with no other option. Had another family member book on us for vacation and they have already changed the flight times twice, with them having to stay an extra day to catch the flight back home. Granted this is just on Spirit, but I'm sure it is similar across the board on other airlines. October is about to bring a whole new level of pain and confusion unfortunately.
