The term 'operational' reasons hides so many issues. Some issues are insignificant and ****e happens. Others are not so insignificant and comes as a result of very poor processes on the airlines front- lack of operational control, lack of crews, lack of staff, etc. I suspect that GB wants to know for the same reason as the rest of us. Was this simply '****e happens' or is it an issue of significant depth that could affect the ongoing viability of Tiger?
