Hello.
Hello, how may I aid you today?
Can you help me to book a flight ticket from DEN to SFO?
Sure, please share me your journey dates.
My travel dates are Sept 30 and Oct 02.
For booking, we need your good name. Please mention it.
I am Mary Turner.
Do you need direct flight or connecting flight?
I need a flight with single connection.
May I know your class preferences?
I prefer to travel in business class.
 We are unable to provide flight in between your journey routes due to some technical up-gradation at destination airport.
Can you please help me to recheck that I would like to depart in evening time.
Sorry, no flights are available.
Ok, not an issue. Thank you for your information.
Thank you for opting us.
