Hello, Jason Jackson here.
Hello. How can I help you?
I have planned to attend my sister's marriage in Houston, so could you please help me to book a flight from PHX to IAH?
That's great to hear. Will you provide your travelling dates?
My preferable dates are from 02/25 to 02/27.
Unfortunately there is no flights found under your requested details.
Ok, thank you for the information.
Welcome, have a nice day.
