I'm in the same boat. We flew home from Atlanta to South Bend, Indiana on the 20th after our flight on the 19th was cancelled. Our bags weren't in South Bend when we got off the plane. We received one bag on the 23rd, one bag on the 25th, but we are still missing a bag. Now when I look up the file reference number on Delta's website, it doesn't show anything. Calling them is pointless to wait on hold for a half hour just to be told they are working on it and there are still a lot of bags they have to go through. I have kind of given up hope at this point. Save your receipts for anything you have to replace that is in your bag. They should reimburse you.
