This is a serious devaluation for me. I often have a multi segment LH itinerary and don't know which legs will clear. I also typically want one or two legs to clear but not all (a couple of C flights mixed in really eases the journey, especially if it gets me into the arrivals lounge at FRA on my way through). Before I would just have two certs and use them when I could. Now I have to request a GPU for every single leg (assuming I have enough in my account). When I get back I have to send back in the ones I haven't used (and wait for the credit, which can take a while).
They just keep whittling away at us.
