Hello, how may I aid you?
assistant
I need to schedule my trip on dates form 05/11 to 05/13 as I have an appointment with my doctor. Can you help me in finding a flight on these dates?
user
Sure, do you have any price limit?
assistant
Yes, I need a less expensive flight within price 500.
user
May I know your airport codes that you wish to board and land?
assistant
I would leave from LAS and arrive at IAH.
user
