Here is a tip to keep handy when you fly on Delta. Delta has a guarantee that if your checked bag doesn’t arrive at the carousel in 20 minutes or less after any domestic flight, you are eligible to receive 2,500 bonus Delta SkyMiles miles. If this happens to you, you need to complete this form no later than three days after your flight’s arrival to receive your miles.
Note that you must be a SkyMiles member at the time of travel to be eligible.

Alaska Airlines has a similar policy as well.
