Hi.
Hello, how may I guide you?
Amy Hernandez here. Can you book me a ticket from IAD  to ORD?
Ok, can I know your preferable dates?
Sure, here are my preferred travelling dates 03/21 and 03/23.
I found a flight 1026 of JetBlue airlines matches with your preferences, can I proceed?
Please book the ticket now.
Your ticket is booked.
Thank you for the service.
Thank you, have a safe flight.
