Hi.
Hello. How may I help you?
I want to book a ticket from LGA to IAD, can you help me?
Sure, can you tell me about your travelling dates?
My travel dates are 04/27 and 04/29.
May I know your name?
Myself Mary Gonzalez.
Sorry for the inconvenience, there is no flight for you on your preferable locations.
No problem, thanks for checking.
Welcome.
