Hi. I am Ronald Thompson.
Hello. How can I assist you?
Please book a flight from SEA to OAK.
Sure, provide me your travelling dates?
Travelling dates are 07/19 and 07/21.
 Do you have any preference?
Yes, I need a connecting flight. I can pay only 200 to a ticket.
Sorry to inform you that no connecting flights were available on your journey dates.
Ok, Thanks for sharing the information.
 Thank you for availing us.
