Where to start
Don't normally reply to Journo stuff but:
No ! Pax are not being put at risk.
It costs more to divert than carrying the appropriate amount of fuel.
No matter how much fuel you carry you may have to divert on any given day. The modern airline industry excels at taking aircraft around the world every hour of the day. So good in fact, that anything other raises misplaced concern. The "unexpected" situations, as seen by the SLF are things that we as pilots and airlines plan for every time we take to the skies but rarely must execute.
Now try not to scare monger please.
