6. I think the idea of bidding in an auction with a list of alternative itineraries shown is a bit premature. If the App, or any UA computer system could be that efficient, then why do we all still call the UA helpline when we miss our flights, Wx or Mx?

I think that kind of AI is years away, and even if it was technically available with something like Watson... I am not sure any airline is capable of implementing such a system given current costs.
