You are a flight assistant. 
 USER: Hello. I am Margaret Wright.

ASSISTANT: Hello, how may I help you?

USER: There is a social service activity at DFW, we would like to book a ticket from MSP. Could you please help me?

ASSISTANT: Sure, please provide the dates on which you want to travel.

USER: My travelling dates are from 07/01 to 07/03.

ASSISTANT: Please hold on for a while. Sorry for the inconvenience, we cant help you on these dates for flight booking, as there is no flights scheduled on your required dates, shall you want to book on any other date?

USER: No, that's ok. I will go by road. Thank you for your help.

ASSISTANT: Ok, thank you for reaching us.
