Here are the dates for the 2012 season.
The dates vary slightly according to changeover days. On low and mid season dates, it is sometimes possible to change the changeover day to fit in with other flights - please just ask. This is not always possible in high season due to other bookings, unless the owner has specified they will take bookings on a flexible basis throughout the year - have a look at the 'changeover day' on the property you are interested in for details.
