Luggage confusion. . . ? Help?

Question

I know in your carry on bag you can only have 3 oz of liquids and they have to be in the clear 1 qt bag and all that. . . but what about in your checked luggage? Can you have liquids in there? Like hair products?

Also, I have sunscreen that is in a spray aerosol type bottle. Is this going to be okay, or should I leave it at home and purchase some more once I'm down there?

Answer 1

Yes, you can carry liquids in your checked baggage.  Be sure to put them in waterproof bags; I also recommend squeezing out a bit of air before packing them.  

The aerosol will be fine as well (baggage holds are pressurized), but again, put it in a waterproof bag.

Answer 2

You can pack liquids and gels in your checked luggage without security problems.

If you do pack liquids in you checked bags be sure to put them first into a plastic bag that will contain any leaks.
