Cargo Freight
I disagree. They will probably get a decent ex gratia payment to "bury" the story as quietly as possible.
If it was a showdog, I wonder if it was insured? and how much does a Rottweiler weigh, even at Warsaw convention rates, that could be a few bucks!
Kokpit
Tightslot is absolutely right - the dog was not a passenger, it was freight and as it was not self loading, it doesn't fit this forum.
