If I make a packed lunch for my kids, can I put jelly on their sandwich of will this be confiscated as a liquid? Do I need to include the sandwich in their quart size baggie? I've never done this before but want to pack a lunch for them to eat during our layover. I'm thinking of getting a few jelly packets and putting in their baggie, but if I can make it ahead of time, why make more work for myself? We have flown at least once a year with our kids, but I've never thought about jelly before.
