I had a look at A3. For the AirnZ fares that she does - W fares. Aegean only gives 0.70 points per mile flown. So also to get rewards was made harder.

The 2nd option would have been OZ but OZ is just too hard for her to get status. Yeah she could have got Silver A3 but she doesn't go anywhere where A3 has lounges so she cannot use her 2? coupons.

I was pretty much left with AC b/c they have a 7yr expiry. ANA/SIA were good too for rewards but the points had a much shorter expiry.
