ASSISTANT: How much you can afford for your flight ticket?

USER: I can afford only 500 for this ticket.

ASSISTANT: Please give me a moment to check for the flight and I will get back to you if there is any flight obtained based on your details. Thank you for waiting, no airlines is providing a flight to your location to book a ticket.
