Funny enough, since August - whenever I take a CX flight, and put my Qantas number on the booking - they make a big thing that although;

My name on the passport is the same as
my name on the ticket which is the same as
my name on my Qantas card

the name they have in their records with Qantas (a short form of my first name - eg Web instead of Webster) does not match and I may have problems getting miles.

The miles always post BUT the emerald part on the boarding card is missing - whereas my gf emerald always shows.

At least it means I can continue reading the newspaper while she has the purser introduce themselves and thanks her for always choosing to fly OW etc.

Although I appreciate the crew going out their way to say hello - she always finds this an awkward moment - and would prefer to avoid it
