Lifetime titanium,and current Ambassador: it's almost utterly pointless! (pardon the pun). Can't use my SNAs, regular "upgrades" aren't real upgrades,and the points truly are low value. More value would be if they would look after Mrs Limey or Moma Limey, but can't even get really beneficial stuff for my family.
Also can't even get a decent breakfast.. eg Moxy D.C... i can have a pastry and an orange juice, not even a breakfast sandwich!
Want a points reservation at the Courtyard in MUC in Oktoberfest... nope... not taking points reservations, but to be fair the cash price wasn't horrible.
