Hello, Robert Baker here.
Hello, how may I help you?
I want to book a ticket to SFO, going to San Francisco for giving presentation at head office of Microsoft, can you book a ticket from New York EWR?
That's great. Sure, may I know your travelling dates?
On Christmas, I want to leave New York  and return will be 12/27.
Ok, can you provide the departure date?
12/25.
There is a flight 1009 of Spirit airlines available for your request. Shall I confirm your booking?
That's great. Please proceed.
Your booking is confirmed.
Thank you.
Thank you for reaching us.
