Here is a cheap one: I would like better information about fast track security and immigration at airports around the world.
Case in point: I have read in a Norwegian forum that LH now gives access to fast track security at OSL for SENs, HONs and C passengers. As an OSL based SEN I have not heard anything from LH, and I can't find confirmation on their website.

At MAN I usually get fastrack access through security as an FTL in Y, but always when travelling in C
The lack of predictability makes this benefit much less usefull
