USER: My journey dates are 11/08 to 11/10.

ASSISTANT: Please give me some time to check the flight availability on your details.

USER: Sure.

ASSISTANT: I have checked with your details, there is a flight 1002 in JetBlue airlines which is one of the best airways providing a flight for you with a 1 halt in your journey, can I confirm your flight ticket booking?

USER: I need a direct flight.

ASSISTANT: Clark, your ticket booking has done on your trip dates to your location. Have a happy journey. Ok, sorry for the trouble. I am in a hurry state in searching a flight for the customers. I am unable to find a flight for you to reserve a flight ticket based on your connection due to sold out of tickets in direct flights for your location.

USER: No issue, thank you.

ASSISTANT: You are most welcome and thank you for reaching us.
