Hello, how may I help you?

This winter I would like to spent my holidays with my grand parents who are living in San Francisco, so could you please book a ticket?

Sure, can you provide the airport codes and travelling dates?

I would like to fly on 10/29 and return back on 10/31. My airport codes are LGA and IAD.

Yes, there is a flight 1005 of Southwest airlines available for your request. Shall I proceed to book the ticket?

Please proceed, if the flight has only a single connection.
