With pressure changes, do they explode/leak?

Are they allowed/disallowed by the airlines (my ticket does not seem to
exclude them - it does exclude flammables, acids, etc)?

There are different propellants - e.g. hydrocarbons, carbon dioxide,
chlorofluorocarbons (CFCs - no longer made - depletes ozone layer).
       - does it make a difference (which propellant) for airlines
         allowing them, or tendency to "drop" their contents?

Does it make a difference if they are in check-in luggage (in aircraft's hold)
vs cabin baggage?

It's my understanding that airlines are not too happy to
carry anything pressurized, like spray cans, oxygen bottles
etc. The containers may fail under pressure changes during
landing.
