in answer to that question...
airlines say and it is stated on ur tickets
that valubles and electrical items should b in ur checked in luggage..
if u read the conditions of carrige for the airlines,,
they r not responsable and will not pay out on any valuble or electrical items that the airline knows or does not know that is inside ur checked luggage..
so in answer to ur question keep them all with u,,
aerosols can b put in ur hand luggage but not 2 many of them. 1 can of deodarent is good,,
