 USER: Hello.

ASSISTANT: Hello. Welcome to Active Travel Agency. How can I help you?

USER: I am Carol Phillips, I am planning to go to Houston for two days for this weekend, and I need to book a flight. Can you please help me?

ASSISTANT: Firstly, our agency is celebrating an anniversary. There is a offer in discount of the ticket, if you book a ticket simultaneously for departure and to return date.

USER: Yes, I am willing to book a return ticket also, so I am thinking of leaving on 03/05 and returning on 03/07.

ASSISTANT: Ok, please tell your travelling locations?

USER: My nearest airport is ATL and destination airport is IAH.

ASSISTANT: UA airline is available with 1 connection. Are you ok with this airline?

USER: Please proceed for booking, make sure the price limit does not exceed 1000.

ASSISTANT: It's a offer time, so the ticket price is just 200.

USER: Ok, proceed for booking.

ASSISTANT: Sure. Your reservation is confirmed with flight 1028.

USER: Thanks for your help.

ASSISTANT: Have a great weekend.

USER: Great service.

ASSISTANT: Thank you and have a nice day.
