Hello Andrew, how can I help you?
assistant
I need to meet my uncle at Houston, so can you please book me a flight ticket on dates 08/25 and 08/27?
user
Ok, may I know your preferred airport codes?
assistant
Yes, my airport codes are Seattle, WA-SEA and TX-HOU.
user
There is a direct flight available on your preferred dates, is that ok for you?
assistant
No, I need a connecting flight.
user
Sorry, there is no flight available with single connection on your preferred dates.
assistant
   That's ok. Thank you for the response.
user
You are welcome and have a nice day.
