The fish story made me so sad---especially when the mother told the Sup that the boy was a loner & the fish was his best (or she might've said only) friend! And actually, I have seen a betta fish make it through TSA. A girl at MDW (not flying WN) got stopped by the TSO but she had already talked to the supervisor and he said it was allowed since it's a requirement for survival, like food for a dog, as long as they could test the water.
Looking forward to watching the other episode; heard the proposal was pretty sweet.
