Hello,.
Hello, how can I aid you?
I am Samuel Wright. Can you please book  a flight ticket from LAX to IAH?
Sure, can you share your trip dates?
My journey dates are, depart on Apr 28th and arrival on Apr 30th.
Do you have any preferences?
My return flight time should be in the evening. And I need a connecting flight.
Sorry, there is no flight on your given dates.
Ok, no problem. Thank you.
