Thank's ^! Didn't know that SEN has to be on all segments on LH et al, should read M&M's explanations first:
Quando utilizza un biglietto premio Lufthansa il Senator può portare con sé un accompagnatore per metà delle miglia. **
** Valido soltanto su voli operati da Lufthansa e dall'Austrian Airlines Group.
Sorry
peter42, looks like your best option is to trade your miles, because an M&M award from Europe to Hawaii is very expensive!
