I read on the TSA website about the regs concerning liquids, gels, and aersols for carry on bags. They call it 3-1-1, but no single container can be larger than 3oz and all must fit in one quart sized ziplock bag. http://www.tsa.gov/311/index.shtm
I was unable to find out if there are restrictions for checked bags? My concerns are for liquids (contact solution for 4 people, etc...) and gels (sunscreen, after burn stuff, etc...) larger than 3oz? Are there any such restrictions?
I didn't think there were, but better safe than sorry.
