Never heard back from Frontier so I got them on the phone today. They were polite but, bottom line: "Too bad, so sad, your dad." They only cover toiletries, clothes, and the actual baggage. Evidently that is standard airline fare. That knife, new, is $357 with the Valloten Auto Conversion. It's a $400 lesson. No, I won't do that again. And it will be a long time before I come up with another $400 for a knife like that. Thanks for the good ideas for the future. I especially like the "take a pic with your phone" one.
If I were twenty years younger I suppose I would go into a giant pissing contest which would net me nothing but a migraine, heartburn, and more anger management classes...:barf::grumpy:
