Hi,
Well, I brought this topic up because after so many years of being a ST E+, I had an incident recently with AF at CDG. I was coming in from Japan on the code-share JAL flight. I did manage to talk my way out of this in Japan, as I think they did not understand much of the ST rules on this.
I could have checked my back all the way to AMS, but I wanted to remove things in CDG for a friend I was meeting there. When I rechecked my bag, the guy made a big fuss and actually printed out an excess baggage payment. I was a bit naive cause after so many years I have never encountered such problems, and told with him that this was eligible since I was E+. I did not know he was right at that time so I was a bit angry.
I was evil when I saw that he did sent my bag through with the priority and destination tag. I did not pay for the excess bagagge (nearly 200 Euros). Though my bag did arrive..
When I did check later back home, I than noticed that this was actually a rule that only members of the specific airline could have such extra baggage. So I was just wondering why.
