Hi. I am Susan White.
Hello, how may I aid you today?
I am looking for a flight from Houston, can you book me a flight ticket from HOU to SFO?
Sure, let me know your travelling dates?
My trip dates are from Apr 8th till Apr 10th.
Could you please share  your budget limit?
Why you will frustrate the customer by asking price. I am ok with any price. Check with it.
Thanks for your details, there no flight found on your journey routes.
I face this issue with your agency every time,. Anyway, thank you.
Thank you for reaching us.
