Over the next few weeks, we’ll be making some changes to our booking class structure. If you usually book a flight in a particular booking class you may find that the fare level is different from what you’ve been used to, but more importantly the Diamond Club miles earned may also differ. The new booking classes will be on sale from 8 February 2011, for travel on or after 1 April 2011.
