Hi.
Hello.
Myself Gregory Williams.
 Williams, how can I help you today?
I want to attend my friend's birthday party, can you please book the flight ticket from SFO to DEN?
Please share your travel dates.
I want to depart on 03/29 and return on 03/31.
Please wait for a while.
Sure.
Sorry Williams, no flight is available on your route.
No problem, thank you for checking.
Thank you for reaching us.
