When an AI can take into account all these subtleties and work reliably then yeh, I'd give it a go. But for now I'm kinda ~ok with the time cost of finding a non-rubbish flight.
I guess this is where 'travel agents' once used to shine.
Also: I want to be _absolutely_ certain the flight was booked -- that nothing was dropped, that no weird API failed to callback, that no letter was dropped from my name, that no silly email parser thought I meant London, Ontario, Canada.
Ps. Cool demo!
