But for routes elite heavy, where the purchase pattern is in the last week or two, a month provides little info. With the old date hack, the user likely understood this but as many don't this many generate disappointment for other. Might make more sense for more leisure routes.
Will agree more than 3 days is good, a month may be at the edge of being meaningful.
