Nothing really life changing for me...

The options that were available previously consisted mainly out of gift cards which were a terrible redemption anyway (like 40k points for $100 on bol.com). I guess they were removed since nobody used them.

In regards to OP: All previous transfer partners are still there for me, but it does trigger me that the amount of partners is so limited with AMEX in NL. In almost every other market there are at least twice the amount of airlines and the redemptions are also much better. 3:1 on Delta is absolutely ridiculous (it's a 1:1 transfer in the UK).
