Hello.
Hello, how best I can help you today?
Can you please help me to book a flight from LAX to DFW?
Sure, please share me your trip dates.
I want to travel on Apr 23 and need to return on Apr 25.
Do you need direct flight or connecting flight?
I need a connecting flight.
If you can help me with your name, I can check with the availability of flights.
I am Melissa King.
 Would you let us know if you have any other preferences?
My depart time must be in the afternoon.
Sorry to say that, there are no flights available on the routes of your journey.
Ok, not an issue. Thank you for the information.
