Hello.
Hello, how may I guide you?
Myself  Debra Wilson, I want to book a flight ticket from San Francisco, My preferable airport codes are from SFO to LGA. Can you help me?
Sure, can I know your preferable dates?
 I want to start my journey on 03/23 and return back on 03/25.
I found a flight 1006 of Delta airlines matches with your preferences, can I proceed?
If it is a connecting flight, you can proceed with that flight booking.
Your ticket is booked.
Thank you for your help in booking.
Thank you, have a great day.
