SO dishonest! SO SAD!

My Viewcam is lost!!!!

I thought once im back I would be blogging about the japan trip. But NO!!
I'm going to blog about something really sad! I was on board Northwest Airline on 16 Nov which touchdown in Singapore at 0035. Was glad to be back. But 2 hours later, I realized that the viewcam was missing. Started to panic. Made several calls to the Changi Airport Terminal 1 and northwest airline. Told them to help do checks. the viewcam was left at seat 23H at the lifejacket area. the staff stated that they could do check but they can only let me know the next morning as they would not be able to call. Sad to say the next morning we received bad news that they did not find it. How could it be!!!!
We were the last ones to leave. So who could have taken it!! Its so frustrating
The Sony SR11 is our brand new view cam and its our first trip to Japan together. Inside it, it holds lots of precious moments me and my boyfriend share during our trip. We really hope to get it back. Can anything be done ???
Any advices as in to how to get it back. If you were the one whom find it would you return?
I know I would!!Please return to me....
