 USER: Hi, Margaret Roberts here.

ASSISTANT: Hello, welcome to southwest airlines. How may I help you?

USER: I am planning to travel to SEA from IAD to attend a medical association meeting, can you book a flight?

ASSISTANT: Ok, can you please provide me your travel dates?

USER: I want to go on 10/29 and return on 10/31. I want 0 connection flight with price 200.

ASSISTANT: I found a flight for you with flight number 1025 and 100 price. Actually there is no flight found with 0 connection, so I have searched for 1 connection limit.

USER: Please do not book my ticket.

ASSISTANT: Ok, fine. Thank you for contacting us.

USER: Thank you for your information.
