I am looking at choosing seats on a Delta flight (code shared with KLM) and Delta shows nearly no available AB/HJ seats together, but KLM shows plenty. Can I call Delta to ask for the seats I see empty on the KLM website? Also, for Delta 223, the Delta site is showing a 2-3-2 configuration, while the KLM site is showing a 2-4-2 configuration. Are the seats that I've picked going to be honored? Thanks in advance!
