Other stuff
From my experience when labeling always use the words " artist supplies" never use the word "paint".
It is also okay to take small bottles of Linseed oil on all the airlines I have dealt with.
You can use a variety of vegetable oils to clean brushes including olive, canola etc. Works well in combination with a little hand soap.
If you are taking a tripod, some airlines consider this as a potential weapon and they require you to add it to your checked luggage.
I have never had issues with bringing back finished panels in small cases as a carry on.
