I have never flown on another airline as code share (KLM plane in this case) with Delta. I will be going to CDG to AMS to get a return my fiinal flight to the U.S. When checking in at CDG which airline do I go to? Delta or KLM who is operating the actual flight? Tickets were bought from delta.com

Other question is baggage. My receipt says 1 free bag per person (I am silver). Looking at the Delta website it appears that silvers get one additional free bag above the standard bag allowance. Is my receipt incorrect and I actually get two free bags?

Thanks in advance.
