I travel a lot with my kids, and feel like I have our routine pretty well down. My kids struggle with the air pressure changes during take off and landing, but trying to get them to drink regular water is tough, so I pack a couple of these packets in their empty water bottles, fill and blend after security check.
You don’t need to use a full packet, either - I just pour enough to give the water flavor and save the rest. The flavors are consistently reliable/good, and it doesn’t taste salty like some of the others.
