Check he http://www.southwest.com/travel_center/toiletry.html
where it says hazardous toiletries can be carried if they are less than
18 ounces each.
Nail polish remover is specifically mentioned.

How much acetone are we talking about? Remember, nail polish remover is

It was much more than that; I would estimate it was about a liter-size
bottle of the stuff. I'm not sure how full it was when it entered the
bag, but it was half full when we found it and re-tightened the cap on
it. Ugh, it smelled *strong* -- even the outside of the canvas bag was
looked like it had been sitting in a puddle.

That is over half a quart. Why anyone needs that much
nail polish remover, I don't know.

I was wondering that myself; now I wish I had asked. Maybe she worked
at a nail salon? Guess I'll never know. :-)

But it appears to be within airline
policy (at least based on what I saw on SWA website).

I don't believe that's the case; it certainly isn't at my airline. Our
page says, "Items such as .... flammable liquids and solids ...are
considered hazardous. Other common items which, in limited quantities,
may be carried within baggage include hairspray, perfume, and certain
medicines which are necessary for customer use during their journey."

I don't think acetone really fits under that description either,
although it's slightly less restrictive than SWA's. They spell it
right out:

http://www.southwest.com/travel_center/chemicals.html

"Southwest Airlines does not allow Customers to carry the following
items in checked or carryon baggage:

* Aerosols (unless medicine or toiletry less than 16 fluid oz.)
* Flammable solvents..."

And acetone is, most definitely, a flammable solvent.


In more general terms, the (now-controlling) TSA permitted/prohibited
items list, it allows "Personal care or toiletries with aerosols, in
limited quantities (such as hairsprays, deodorants)" in both checked
and carry-on luggage.

But under the "Flammable Items" list at the end, every single item is
prohibited, including paint thinners and bleach (under the next
section).

You can check that list out he
