Hi, I'd like to book a round-trip flight from San Francisco to Houston.
Okay any preferences for this flight?
I'd like to leave in the morning.
What class would you like to fly?
Let's go with first.
Least expensive first-class flight with $1,237 leaving at 6:45 PM.
And is there any nonstop flight?
I found a nonstop flight for 1390$ leaving at 7:10 PM. Would you like that?
Yeah, that sounds perfect.
That is with United Airlines.
Perfect. Thank you.
Okay enjoy.
