Flew dtw bos ams bru in August. Bags didn't make the tight connection in AMS. I reported to the "lost and found services" (outsourced baggage handler in BRU).

I arrived on Thursday. They found one bag Saturday afternoon and one Sunday night. Bags were set up for delivery Monday night to where I was staying in Maastricht. I was leaving back for Brussels Monday night, since I was flying home on Tuesday. I just had them deliver to my hotel near brussels.

I tweeted klm and delta almost daily while waiting. Delta referred me to KLM. I bought about $80 in clothes, toiletries, to get me through my stay with family. Submitted claim to KLM, delta ended up contacting me and sending me a check for expenses. (I think they got off easy, since I only had the clothes on my back, but I was cheap in my purchases in case I didn't get reimbursed fully.)

They required receipts, paperwork from luggage office, and bag tags. The form is fillable online and needed scans of docs.

I hope they find your bags quickly, and that patience is something your 10 year old possesses
