on an international flight an msr can be a pain in the arse - the bottle may not get on the plane at all ... chalk isn't an issue at all.
just put it all in your check-in lugguage.
interstate flights almost anything goes, it's bloody rediculous really, but I'm not complaining - I've flown from Canberra to Adelaide with fireworks in my backpack, and (unbeknown to me) flew all around the US with a leatherman in my carry-on!!! |
