Delta made me check my carry-on pelican case while boarding the plane, even though there was ample room in the overhead bins above my seat. I originally hadn't been willing to check my bag as it contained all of my work gear and I wanted to keep a close eye on it. When I got home I found out that they had rifled through all of my belongings and misplaced part of the protective foam insert (making the case useless) as well as indents in both of my laptops. My speakers cut in and out on one of my laptops now and is not fit for work purposes. So they RUINED my pelican case and devalued BOTH of my laptops.I didn't have any time to file the claim when I got home and the next day after I finished my claim, I received a response informing me that I was outside the 24-hour window that their policy allows for, and they were closing my case. Their smug representative assured me that they will exceed my expectations in the future, what a joke! I was only asking the equivalent of 2 flights to repair my work gear and they would've made a lifelong loyal customer out of the ordeal, but their cost analysis must be poorly lacking.
