http://www.tsa.gov/public/interapp/editorial/editorial_1012.xmlThe Word file has a long list of what is an is not allowed in both carry on and checked.
I am not too sure that the people who work the checkin always follow what is on the list, but ...
"all lighters" are prohibited from carry on and lighters with fuel cannot be checked. Strike anywhere matches are also a no no.
I would not be suprised if a Strike Spark would be considered as "all lighters".
The rules do state that up to four books of saftey matches can be in carry on (but not in checked bags). I have carried book matches in carry on. Not my idea of the best choice, but at least they are better than nothing.
Anyway, probably a good idea to check the TSA site before you fly.
