You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello, how can I help you?

USER: George Clark here. I want to book a flight to attend an interview in Houston - HOU, can you find a flight from DEN?

ASSISTANT: Sure, can you share your travelling dates?

USER: My journey dates are from 08/23 to 08/25.

ASSISTANT: Do you have any specifications?

USER: I need a stopover between my journey.

ASSISTANT: There is a connecting flight with number 1024 in airline UA, the fare is 800.

USER: But my budget is only 500, can I get discount as I am a master card holder?

ASSISTANT: Sorry, there is no flight with the price limit 500.

USER: That's very disappointing news for me. Anyways, than you for checking.

ASSISTANT: Thank you for reaching us.

USER: You are most welcome.
