Oh Boy!!!! Leave it to you Charm to start a ruckus
You were very smart to have pulled up your shirt and showed your accessory. Otherwise I would be afraid of what could have happened to you and your peg. Security would have thought you were wired for sure. After reading your post, I will think twice before I do traveling by plane with formula. Im not able to do the feedings by syringe, I get sick when I have used that method.
Thanks for sharing your experiences. Now Im looking in the friends section to hear about your trip.
