Right, and what if it gets spooked and just takes off? That leash would be useless against those wings. You'd have a bright blue problem flying into the ceiling lights.
Honestly danielr94, the leash is the part that gets me... like, what's the plan if that bird decides it wants to fly? That's not a dog, it's a creature built for the canopy. Seems like a huge gamble in a space full of sliding doors and loud noises. Someone's just hoping the macaw stays chill while luggage carts zoom by. That's a level of trust I don't think I could ever have with a parrot.
