My name is Donald Walker. I need your help in booking a flight ticket from OAK to BOS.

Can I know the travel dates?

Sure, my departure date is on 10/31 and the return date is on 11/02.

Just hold on for a moment.

I'm sorry Donald, there are no flights matching with your dates.

That's really sad. Anyways, thank you for your help.
