ugh, that is so stupid. they don't even know their own new rules. Once, my husband was carrying a classified doc. and NO ONE could look at it. He works in missile defense.. they didn't know what to do..too funny actually.

Anyway, I have never traveled w/those containers, so clueless.. Just I guess call the airline or airports you'll be going thru.. Chances are they won't even know where to direct the call and you'll get a diff answer every time.

I wouldn't even bother bringing something like that, esp glass. Try the toddler puffs/fruit bites or toddler meals in the box, plastic container... instead
