I would prefer to travel from NY - EWR to NY - LGA on the occasion of my nephew birthday party. Can you  book a flight ticket for me?
Sure, I am here to help you. Can you please share your journey dates and price?
Sure, I need to fly on 07/04 and 07/06. Please make sure price limit should not cross 200.
Please wait a moment, I will check and get back to you.

We found a flight with Hawaiian airlines, flight number is 1007 and price is 100 with one connection. Shall I proceed?
Yes, you can.
OK, your ticket has been booked. Have a safe journey.
