It is always an interesting read as to what is allowed/not allowed.
Defense sprays are allowed in checked luggage but AA bans even in checked luggage.
I thought at one time defense sprays we not allowed on the Dutch side. This is going back a few years. Might be mistaken.

This gave me a laugh from the TSA list.

For Checked bags: We asked the Magic 8 Ball and it told us…It is certain!
