Hello, Robert Martinez here.
Hello Mr. Martinez.  How can I help you today?
I am planning to visit Heritage Square in Phoenix, could you book a ticket for me from IAH to PHX?
Sure thing.  When do you plan on making this trip.
I am travelling on 05/08 and 05/10.
Looks like there's a fairly empty flight operated by American.  The seat is in economy and the total would be 100.
Please book my ticket.
Your flights been booked.  Please contact us if you have any questions.
Thank you for assisting me.
Your welcome.  Have a nice day.
