The card number is part of the eticket. DL just has to pull the original ticket (assuming it was exchanged subsequently) and will have card. They can also hust ask for it.
File for EC261 delay compensation as a separate thing with KLM. Don't mention you already sent in a message. Too many things jumbled together just leads to confusion.
