Hello, Jennifer Thompson here.
Hello, how may I assist you?
I want you to book a ticket for me from EWR to LAS, could you?
Sure, could you please provide your travelling dates to search for the flight?
I prefer my outing happens from July 18 and end by July 20.
May I know your price limit for this trip?
I can afford up to 200 for this trip.
Sorry to say, no flight is available for you.
That's not expected from you.  Anyways thanks for your time.
Thank you for reaching us, have a nice day.
