Hi.
Hello.
I am John Wilson.
How can I help you John?
As my budget is low, I need a flight with fare 200. Can you help me in booking?
Ok, I will help you in booking a ticket under price of  200. Could you please provide your travelling dates?
I planned my trip on 11/08 and return on 11/10.
Mention you corresponding airport codes to reserve a ticket?
I will start from IAD and land at HOU.
There is a Spirit 1017 airline with fare of 200 which matches your requirements. Shall I proceed with that airline?
That's great, you can book it.
Your booking has been confirmed on 1017 with name of John Wilson.
Thank you for helping.
Thank you for approaching us.
