It's certainly impressive. I would like to know if it could search multiple airlines directly to find the best price and best route based on my personal preferences. For example, I don't like earlier flights unless it is ~60% cheaper. And if it can handle check-in for me so I don't have to be logging in 24 hours before, and if I am offered an upgrade, it could automatically purchase.
There are dozens of factors to consider, and everyone weights them all differently. Even humans aren’t great at this, and it’s not an intelligence problem that “AGI” can solve.
