Indeed.

I lost my checked bags nearly 40 times so far ... and always was I reunited with them. Mostly on the same day, occasionally 3 days later, more commonly a week or two later, once 8 weeks later.... but never did they get lost for good.

I also vaguely remember - but fail to find the evidence - a UK court decision that if you have contact labels inside of the bag then the airline cannot simply claim a loss but this is evidence for theft/fraud and hence you can take them court and the limits for losses do not apply.
