Hi.
Hello, how can I assist you?
By mistake I have booked a flight for round trip so, can you please change my existing reservation to New York airport?
Sure, we are here to help you.
Thank you.
May I know your name to check your details in our reservation list?
Mark King is my name.
Ok, give me sometime to check and I will revert to you with the current status.
OK.
Thank you for your valuable time, we are sorry to inform you that there is no reservation found on your name to do modifications.
Ok, that's not a problem. Leave it. Thanks for your quick response.
Thank you for consulting us.
