Hello.
Hello. How may I assist you?
Can you please aid me in reserving the flight ticket to reach Washington from Boston?
To proceed further I need your source and destination codes.
Thank you.  My source and destination airport codes are BOS and IAD.
May I know your trip dates to reserve your seat.
Please reserve the flight ticket for these dates Sept 5th and Sept 7th.
 On whose name I have to book the flight ticket?
My name is Stephen Jones.
 Could you let us know if you have any class preference?
No, I didn't have any class preference but I prefer a direct flight to travel.
Are you looking for any other help from my side please?
No, thanks for asking.
We are unable to provide flight in between your journey routes due to some technical up-gradation at destination airport.
It's ok, not a problem with that. Thank you for searching the flights for me.
Welcome, have a good day.
