Hi, I'm looking to book a ticket with normal-cost airline. Please help me with it.
Very well. Could I please get your name?
Oh yes, Sorry I forgot to introduce myself. I'm Paul Lewis.
Hi Paul.  Do you mind sharing the details of your trip with me?
Sure. I need to book a round trip from DEN to BOS and back to DEN please. And my travel dates would be November 4th to November 6th.
Alright.  Please give me one moment while I search for a flight.
Yes, take your time.
I've found one flight that matches your request. It's a flight operated by UA in economy for 100.  Shall I book it?
Oh perfect. I think you can go ahead and book it.
Your flight has been booked.  Is there anything else that I can help you with?
No, that is it for today. But I would like to say you have a great service. Thank you, have a good day ahead.
Your welcome. Please contact us again if you have any questions regarding your flight.  Have a nice day.
