Hi.
Hello. How may I help you?
I am Melissa Carter.
Nice to meet you Melissa.
I would like to attend my friend wedding at Denver, can you please help me to book a flight ticket from IAD to DEN?
Sure, tell me your travel dates please?
Sure, my journey dates are May 12 and May 14.
Do you have any preferences?
My departing time is afternoon.
Ok. Thanks for waiting. But I am sorry to say that there are no flights available.
That's ok, thank you for your information.
Thank you.
