Thank you for considering my request. Myself Andrew Thompson.
Please be on hold.
Sure, I will wait for your response.
Here, I have found your reservation. May I know the planned travel dates?
My planned new travel dates are from Feb 13 to Feb 15.
Please provide me the airport codes.
My new preferable airport codes are ORD and LAX.
Do you have any specifications?
Yes, I need a flight with connection limit-1.
Here, I found a flight with 1 connection and airfare is about 100. Shall I proceed in booking?
  That's fine for me, you can proceed with that ticket booking.
