Hello.
Hello. How may I help you?
 I have booked a flight ticket to New York city to attend a meeting but due to some issues in the office, our manager decided to conduct the meeting in Phoenix. So, I need to change the travel airport codes. Can you please help me in changing the ticket details?
Ok, may I know your name to check your reservation status?
Yes, I am Robert King.
Ok, please allow me a moment to check for the previous reservation.
Sure.
Sorry, there is no reservation found under your name to change your reservation.
Ok, not a problem. Thank you for your help.
Thanks for choosing us, have a good day.
