Hi. I'd like help getting a flight from Sacramento to Houston.
Hi. How can I help you? Okay, sure. When would you like to leave?
I would like to leave this afternoon and return in five days.
Okay. Any preferences?
I would like for the total travel time to be the shortest possible. And I'd also like business class.
The shortest possible travel time of business classes cost you $1,076. Flight will be leaving at 4:50 p.m. with one layover.
Okay.
Would you like to book a return flight?
Yes.
Is that with same preferences?
Yes.
It will cost you $1,405 and will be  leaving at 9:44 p.m. This non-stop flight will take 3 hours and 57 minutes of travel time.
Okay.
Would you like me to book that?
Yes.
Okay. You're all set. I've booked and sent it to your mail. Enjoy your flight.
