Hello. Kenneth Phillips here.
Hello. How can I help you?
I like to go PHL for my vacations from my current location DFW.
Ok, can I know the travel dates please?
 I have planned to book my round trip ticket from 12/26 to 12/28. Please make sure this, my price limit is 500 and connection limit is 1.
Ok, please wait a moment.
Sure.
I found a flight for you with single connection and price is 100. Shall I book it?
That's nice. Please proceed my ticket booking.
I have booked your ticket with flight number 1011 and airline is JetBlue.
Thank you.
Thank you for reaching us, have a safe journey.
