Would you like to travel in a connecting flight or a direct flight?
I need a flight with single connection.
May I know your name please?
Myself Stephen Davis.
Is there any other preferences that you would like to add before booking?
No, I didn't have any other specifications?
Let me check the availability of flights and revert to you.
