Hello, Jennifer Wilson here.
Hello, how may I assist you today?
I planned to attend for an interview in DEN, can you please help me to book a flight ticket from IAD?
Jennifer Wilson, may I know your planned dates for this journey please?
I would like to travel on 05/07 and  05/09.
Please wait for a while, till I check available flights on route for you.
Sure.
There is a direct flight by Frontier airlines at the price of 100, Shall I book it?
No, please don't book it. I want a 1 connecting flight.
Ok, let me check a flight with 1 connection for you.
Ok.
Sorry Jennifer Wilson, no flights for you with single connection.
Ok, not an issue.
Thank you for reaching our services, have a great day.
