Reply To: Which Star Alliance programme to join?

you can match on wheretocredit dot com, to check what booking class (=subset of cabin class) on which airline will earn you in which/other airline’s program.

aa a rule of thumb avios/points/miles earned might increase according to cabin class, but tier points(ie status points) or their equivalent rarely do, tier points are normally assigned to a route by an airline at a flat rate roughly according to distance.
