Balpa and the CAA are two cherished (!) British aviation institutions that have not been fit for purpose for a very long time, if ever. One a well trodden route to the management structure and the other a time serving bunch of bureaucrats also looking to hop back into industry at a management level. Seen it all before. I am also ex Virgin and I can confirm that the endless time zone changes have a very debilitating affect on personal health. However, Safety is our biggest priority. Hilarious.
