Doesn't matter what you ask for. DL does this on a formulaic basis. This will be 5-10K.
In addition, DL will cover your reasonable out of pocket expenses and reserves the right to see the receipts. Best practice for quick reimbursement is to submit the receipts with the claim. $100 for 2 days is pretty reasonable, so not likely much to be worried about.
Bags sometimes go missing. As you can see, they almost always are located and reunited with the owner in 2-3 days. No system is perfect.
The Twitter thing is b.s. DOT requires reports from carriers and your bag will be reported as a statistic.
