Exploded battery on a Macbook Air (Macboom Air)

Question

The battery on my Macbook Air suddenly became very hot and the whole aluminium unibody burst swollen. There is no warranty left but how does Apple handle such occasions?
It was shortly after a flight where the Macbook Air was in the cargo section of the airplane. It could have resulted a serious threat to the flight.
Here's a picture of the swollen Macbook Air:

That's a clear cut mistreatment of the Air.  
The Air never should have gone in the freezing cargo hold with also lack of pressurization!
The battery got extremely cold in the cargo section, and low pressure causing cell interior rupture.  No the flight was not under any serious threat.
Don't dare use it in its current state,... contact Apple for replacing the lithium battery.
