I'm dumbfounded. I would never check any article the loss or damage of which is expressly disclaimed by every major airline. Check the Conditions of Carriage of AA and UA (assuming the OP flew one of those, given the routing) - neither airline will cover any damage or loss to a laptop in a checked bag. I suspect that no airline in the world would cover such loss.
Earlier this week, a different new poster related the theft of his $1,300 digital camera and lens from a checked bag on AA in the AA forum.
Was there an article in the news lately painting Flyertalk as a "I checked a valuable article and it disappeard from my checked bag and I'm wondering what my options are?" kind of website?
