I am flying soon and I will have a honey jar in my checked baggage.

Since it is now brand new (I already used part of it), it is no longer hermetically closed, so I am quite afraid it will spill on the rest of the things I will be carrying.

Is there any trick on how to pack/protect such jars?

I was planning to use some tight plastic bag, then some paper around it (to absorbe possible spills) and finally another bag.
