Hello.
Hello, how can I assist you?
I am planning to visit Philadelphia, will you help me in booking the flight ticket form IAD to PHL?
Sure, may I know your travel dates?
My travelling dates are Oct 15 and Oct 17.
Do you have any specifications?
I need a connecting flight.
Ok, please wait  a minute.
Make sure my class must be economy.
We found an airline UA with flight 1023 having a fare 100 with single connection. Shall I proceed with booking for economy class?
You can proceed booking with the name David Lee.
Ok, your booking has been processed.
Thank you for helping me.
Thank you.
