How often do they release the used aircraft? Monday to Sunday? when is the best day to check?
As far as I remember, but not entirely sure, it has been randomized in a way that there are no specific planned dates/times for the refreshing of the used market. There have been threats about it before in the forum.

There is a specific time of day they are released ;) If you can watch a day or 2, its pretty easy to find the approximate time. The days are less predicatable.
