Hi, I'd like getting a flight from San Francisco to Houston.
Okay. Can you give me some specifications?
I would like to leave today and return in 3 days.
What seating class do you prefer?
I prefer business class.
Do you prefer non stop or layover?
I'd prefer the cheapest flight possible.
Okay.
I want to leave as early as possible.
Do you want to leave in the morning or afternoon flight? Let me check for you.
Okay. Okay. Sounds good, book it.
I found a flight for you. American airlines, departs at 8:30 a.m., arrives at 2:18 p.m. You got it, enjoy your flight.
