Good grief, I wish I could give you specific help relating to your queries, but I will be taking a plane at the end of this month for only the second
time in my life, so I really can't chime in with anything worthwhile.
However, I did want to express my encouragement! I hope you have an awesome trip, and something tells me that you will. Just think of what would happen if a big fuss was made about your unique situation at an airport! It would be a PR disaster
!!! No one is going to make waves when it comes to a sensitive issue such as an ostomy. Trust me, they would end up looking extremely foolish in the end. And if something does happen, let us know and we'll start writing angry letters!
Seriously, have a great trip.
