I'm looking for a round-trip commercial airline flight.
Sure thing. Where to?
From San Francisco to Miami.
When would you like to leave and come back?
I would like to depart today and then come back in four days on 17th.
Any other preferences?
I would like the latest departure time possible and the latest return time possible. In addition, I would like a non-stop flight.
For $655 at 10:40 pm, nonstop with American Airlines. Would you like that?
Yes.
Would you like to book your return flight?
Yes.
Under the same preferences?
Yes.
9:35 pm, $659, non stop.
Sounds good.
Okay, I'll book, enjoy your flight.
