Hi all, we are leaving for Disney on Saturday and flying Southwest Airlines. We have never flown as a family before, so I'm having to figure out some packing along the way. With Southwest, we get 2 checked bags per person and as a family of 4, I know we won't be needing 8 checked bags! lol I'm thinking of packing one of the extra suitcases with food. I know we could go with Amazon Pantry or Garden Grocer, but if I could run to Walmart and get all the fruit snacks, goldfish, etc and already have them with me, I think that would be the easiest and probably cheaper. But I was wondering if I put a smaller insulated lunchbox in the suitcase, if I could bring things like yogurts or small bottle of milk with some Yeti ice packs?? I'm not worried about them staying cold. We have a relatively short trip to the airport and less than 2 hour flight. If for some reason we were delayed, I might lose a few dollars worth of yogurts. I'm more concerned if they would confiscate something like that? Anyone have experience with this? Thanks!
