Hi.
Hello.
I am Benjamin King.
King, how can I assist you today?
 I am planning to reserve a plane ticket from LAS to PHL, can you please help me out?
Sure, can you please tell me your trip dates?
Sure, my travelling dates are from 06/02 to 06/04.
Ok, please wait for a moment.
Ok.
Sorry King, there are no flights available on your preferred dates.
No problem, thank you.
Thank you for contacting us and have a nice day.
