Hi.
Hello.
I am David Miller.
How may I assist you David?
I gave wrong airport codes in my previous reservation, so can you help me for changing an existing reservation?
Sure, I will be helping you with it.
Thank you.
Please give me a moment, and I will revert back to you with the information.
Ok, I will wait for your response.
Sorry to tell you David Miller, but no reservation is found by your name.
Oh! I think my friend already changed my reservation.
Thank you for choosing our agency, keep reaching us for your further bookings.
Thank you for your support.
Have a nice day.
